Tower of London

Architecture

Layout

The Tower's strongest and most impressive defences overlooked Saxon London, which archaeologist Alan Vince suggests was deliberate. It would have visually dominated the surrounding area and stood out to traffic on the River Thames. The castle is made up of three "wards", or enclosures. The innermost ward contains the White Tower and is the earliest phase of the castle. Encircling it to the north, east, and west is the inner ward, built during the reign of Richard I (1189–1199). Finally, there is the outer ward which encompasses the castle and was built under Edward I. Although there were several phases of expansion after William the Conqueror founded the Tower of London, the general layout has remained the same since Edward I completed his rebuild in 1285.

The castle encloses an area of almost 12 acres (4.9 hectares) with a further 6 acres (2.4 ha) around the Tower of London constituting the Tower Liberties – land under the direct influence of the castle and cleared for military reasons. The precursor of the Liberties was laid out in the 13th century when Henry III ordered that a strip of land adjacent to the castle be kept clear. Despite popular fiction, the Tower of London never had a permanent torture chamber, although the basement of the White Tower housed a rack in later periods. Tower Wharf was built on the bank of the Thames under Edward I and was expanded to its current size during the reign of Richard II (1377–1399).

White Tower

The White Tower is a keep (also known as a donjon), which was often the strongest structure in a medieval castle, and contained lodgings suitable for the lord – in this case, the king or his representative. According to military historian R. Allen Brown, "The great tower [White Tower] was also, by virtue of its strength, majesty and lordly accommodation, the donjon par excellence". As one of the largest keeps in the Christian world, the White Tower has been described as "the most complete eleventh-century palace in Europe".

The White Tower, not including its projecting corner towers, measures 36 by 32 metres (118 by 105 ft) at the base, and is 27 m (90 ft) high at the southern battlements. The structure was originally three storeys high, with a basement, an entrance level above, and an upper floor. The entrance, as is usual in Norman keeps, was above ground, in this case on the south face, and accessed via a wooden staircase which could be removed in the event of an attack. It was probably during Henry II's reign (1154–1189) that a forebuilding was added to the south side of the tower to provide extra defences to the entrance, but it has not survived. Each floor was divided into three chambers, the largest in the west, a smaller room in the north-east, and the chapel taking up the entrance and upper floors of the south-east. At the western corners of the building are square towers, while to the north-east a round tower houses a spiral staircase. At the south-east corner there is a larger semi-circular projection which accommodates the apse of the chapel. As the building was intended to be a comfortable residence as well as a stronghold, latrines were built into the walls, and four fireplaces provided warmth.

The main building material is Kentish ragstone, although some local mudstone was also used. Caen stone was imported from northern France to provide details in the Tower's facing, although little of the original material survives as it was replaced with Portland stone in the 17th and 18th centuries. Reigate stone was also used as ashlar and for carved details. Its location, in the lower courses of the building and at higher levels corresponding to a building break, suggest it was readily available and may have been used when access to Caen stone was restricted. As most of the Tower's windows were enlarged in the 18th century, only two original – albeit restored – examples remain, in the south wall at the gallery level.

The tower was terraced into the side of a mound, so the northern side of the basement is partially below ground level. As was typical of most keeps, the bottom floor was an undercroft used for storage. One of the rooms contained a well. Although the layout has remained the same since the tower's construction, the interior of the basement dates mostly from the 18th century when the floor was lowered and the pre-existing timber vaults were replaced with brick counterparts. The basement is lit through small slits.

Innermost ward

The innermost ward encloses an area immediately south of the White Tower, stretching to what was once the edge of the River Thames. As was the case at other castles, such as the 11th-century Hen Domen, the innermost ward was probably filled with timber buildings from the Tower's foundation. Exactly when the royal lodgings began to encroach from the White Tower into the innermost ward is uncertain, although it had happened by the 1170s. The lodgings were renovated and elaborated during the 1220s and 1230s, becoming comparable with other palatial residences such as Windsor Castle. Construction of Wakefield and Lanthorn Towers – located at the corners of the innermost ward's wall along the river – began around 1220. They probably served as private residences for the queen and king respectively.

The earliest evidence for how the royal chambers were decorated comes from Henry III's reign: the queen's chamber was whitewashed, and painted with flowers and imitation stonework. A great hall existed in the south of the ward, between the two towers. It was similar to, although slightly smaller than, that also built by Henry III at Winchester Castle. Near Wakefield Tower was a postern gate which allowed private access to the king's apartments. The innermost ward was originally surrounded by a protective ditch, which had been filled in by the 1220s. Around this time, a kitchen was built in the ward. Between 1666 and 1676, the innermost ward was transformed and the palace buildings removed. The area around the White Tower was cleared so that anyone approaching would have to cross open ground. The Jewel House was demolished, and the Crown Jewels moved to Martin Tower.

Inner ward

The inner ward was created during Richard the Lionheart's reign, when a moat was dug to the west of the innermost ward, effectively doubling the castle's size. Henry III created the ward's east and north walls, and the ward's dimensions remain to this day. Most of Henry's work survives, and only two of the nine towers he constructed have been completely rebuilt. Between the Wakefield and Lanthorn Towers, the innermost ward's wall also serves as a curtain wall for the inner ward. The main entrance to the inner ward would have been through a gatehouse, most likely in the west wall on the site of what is now Beauchamp Tower. The inner ward's western curtain wall was rebuilt by Edward I. The 13th-century Beauchamp Tower marks the first large-scale use of brick as a building material in Britain, since the 5th-century departure of the Romans. The Beauchamp Tower is one of 13 towers that stud the curtain wall. Clockwise from the south-west corner they are: Bell, Beauchamp, Devereux, Flint, Bowyer, Brick, Martin, Constable, Broad Arrow, Salt, Lanthorn, Wakefield, and the Bloody Tower. While these towers provided positions from which flanking fire could be deployed against a potential enemy, they also contained accommodation. As its name suggests, Bell Tower housed a belfry, its purpose to raise the alarm in the event of an attack. The royal bow-maker, responsible for making longbows, crossbows, catapults, and other siege and hand weapons, had a workshop in the Bowyer Tower. A turret at the top of Lanthorn Tower was used as a beacon by traffic approaching the Tower at night.

As a result of Henry's expansion, St Peter ad Vincula, a Norman chapel which had previously stood outside the Tower, was incorporated into the castle. Henry decorated the chapel by adding glazed windows, and stalls for himself and his queen. It was rebuilt by Edward I at a cost of over £300 and again by Henry VIII in 1519; the current building dates from this period, although the chapel was refurbished in the 19th century. Immediately west of Wakefield Tower, the Bloody Tower was built at the same time as the inner ward's curtain wall, and as a water-gate provided access to the castle from the River Thames. It was a simple structure, protected by a portcullis and gate. The Bloody Tower acquired its name in the 16th century, as it was believed to be the site of the murder of the Princes in the Tower. Between 1339 and 1341, a gatehouse was built into the curtain wall between Bell and Salt Towers. During the Tudor period, a range of buildings for the storage of munitions was built along the inside of the north inner ward. The castle buildings were remodelled during the Stuart period, mostly under the auspices of the Office of Ordnance. In 1663, just over £4,000 was spent building a new storehouse (now known as the New Armouries) in the inner ward. Construction of the Grand Storehouse north of the White Tower began in 1688, on the same site as the dilapidated Tudor range of storehouses; it was destroyed by fire in 1841. The Waterloo Block, a former barracks in the castellated Gothic Revival style with Domestic Tudor details, was built on the site and remains to this day, housing the Crown Jewels on the ground floor.

Outer ward

A third ward was created during Edward I's extension to the Tower, as the narrow enclosure completely surrounded the castle. At the same time a bastion known as Legge's Mount was built at the castle's northwest corner. Brass Mount, the bastion in the northeast corner, was a later addition. The three rectangular towers along the east wall 15 metres (49 ft) apart were dismantled in 1843. Although the bastions have often been ascribed to the Tudor period, there is no evidence to support this; archaeological investigations suggest that Legge's Mount dates from the reign of Edward I. Blocked battlements (also known as crenellations) in the south side of Legge's Mount are the only surviving medieval battlements at the Tower of London (the rest are Victorian replacements). A new 50-metre (160 ft) moat was dug beyond the castle's new limits; it was originally 4.5 metres (15 ft) deeper in the middle than it is today. With the addition of a new curtain wall, the old main entrance to the Tower of London was obscured and made redundant; a new entrance was created in the southwest corner of the external wall circuit. The complex consisted of an inner and an outer gatehouse and a barbican, which became known as the Lion Tower as it was associated with the animals as part of the Royal Menagerie since at least the 1330s. The Lion Tower itself no longer survives.

Edward extended the south side of the Tower of London onto land that had previously been submerged by the River Thames. In this wall, he built St Thomas's Tower between 1275 and 1279; later known as Traitors' Gate, it replaced the Bloody Tower as the castle's water-gate. The building is unique in England, and the closest parallel is the now demolished water-gate at the Louvre in Paris. The dock was covered with arrowslits in case of an attack on the castle from the river; there was also a portcullis at the entrance to control who entered. There were luxurious lodgings on the first floor. Edward also moved the Royal Mint into the Tower; its exact location early on is unknown, although it was probably in either the outer ward or the Lion Tower. By 1560, the Mint was located in a building in the outer ward near Salt Tower. Between 1348 and 1355, a second water-gate, Cradle Tower, was added east of St Thomas's Tower for the king's private use.

History

Foundation and early history

Victorious at the Battle of Hastings on 14 October 1066, the invading Duke of Normandy, William the Conqueror, spent the rest of the year securing his holdings by fortifying key positions. He founded several castles along the way, but took a circuitous route toward London; only when he reached Canterbury did he turn towards England's largest city. As the fortified bridge into London was held by Saxon troops, he decided instead to ravage Southwark before continuing his journey around southern England. A series of Norman victories along the route cut the city's supply lines and in December 1066, isolated and intimidated, its leaders yielded London without a fight. Between 1066 and 1087, William established 36 castles, although references in the Domesday Book indicate that many more were founded by his subordinates. The Normans undertook what has been described as "the most extensive and concentrated programme of castle-building in the whole history of feudal Europe". They were multi-purpose buildings, serving as fortifications (used as a base of operations in enemy territory), centres of administration, and residences.

William sent an advance party to prepare the city for his entrance, to celebrate his victory and found a castle; in the words of William's biographer, William of Poitiers, "certain fortifications were completed in the city against the restlessness of the huge and brutal populace. For he [William] realised that it was of the first importance to overawe the Londoners". At the time, London was the largest town in England; the foundation of Westminster Abbey and the old Palace of Westminster under Edward the Confessor had marked it as a centre of governance, and with a prosperous port it was important for the Normans to establish control over the settlement. The other two castles in London – Baynard's Castle and Montfichet's Castle – were established at the same time. The fortification that would later become known as the Tower of London was built onto the south-east corner of the Roman town walls, using them as prefabricated defences, with the River Thames providing additional protection from the south. This earliest phase of the castle would have been enclosed by a ditch and defended by a timber palisade, and probably had accommodation suitable for William.

Most of the early Norman castles were built from timber, but by the end of the 11th century a few, including the Tower of London, had been renovated or replaced with stone. Work on the White Tower – which gives the whole castle its name – is usually considered to have begun in 1078, however the exact date is uncertain. William made Gundulf, Bishop of Rochester, responsible for its construction, although it may not have been completed until after William's death in 1087. The White Tower is the earliest stone keep in England, and was the strongest point of the early castle. It also contained grand accommodation for the king. At the latest, it was probably finished by 1100 when Bishop Ranulf Flambard was imprisoned there. Flambard was loathed by the English for exacting harsh taxes. Although he is the first recorded prisoner held in the Tower, he was also the first person to escape from it, using a smuggled rope secreted in a butt of wine. He was held in luxury and permitted servants, but on 2 February 1101 he hosted a banquet for his captors. After plying them with drink, when no one was looking he lowered himself from a secluded chamber, and out of the Tower. The escape came as such a surprise that one contemporary chronicler accused the bishop of witchcraft.

Expansion

The castle probably retained its form as established by 1100 until the reign of Richard I (1189–1199). The castle was extended under William Longchamp, King Richard's Lord Chancellor and the man in charge of England while he was on crusade. The Pipe rolls record £2,881 1s 10d spent at the Tower of London between 3 December 1189 and 11 November 1190, from an estimated £7,000 spent by Richard on castle building in England. According to the contemporary chronicler Roger of Howden, Longchamp dug a moat around the castle and tried in vain to fill it from the Thames. Longchamp was also Constable of the Tower, and undertook its expansion while preparing for war with King Richard's younger brother, Prince John, who in Richard's absence arrived in England to try to seize power. As Longchamp's main fortress, he made the Tower as strong as possible. The new fortifications were first tested in October 1191, when the Tower was besieged for the first time in its history. Longchamp capitulated to John after just three days, deciding he had more to gain from surrender than prolonging the siege.

John succeeded Richard as king in 1199, but his rule proved unpopular with many of his barons, who in response moved against him. In 1214, while the king was at Windsor Castle, Robert Fitzwalter led an army into London and laid siege to the Tower. Although under-garrisoned, the Tower resisted and the siege was lifted once John signed Magna Carta. The king reneged on his promises of reform, leading to the outbreak of the First Barons' War. Even after Magna Carta was signed, Fitzwalter maintained his control of London. During the war, the Tower's garrison joined forces with the barons. John was deposed in 1216 and the barons offered the English throne to Prince Louis, the eldest son of the French king. However, after John's death in October 1216, many began to support the claim of his eldest son, Henry III. War continued between the factions supporting Louis and Henry, with Fitzwalter supporting Louis. Fitzwalter was still in control of London and the Tower, both of which held out until it was clear that Henry III's supporters would prevail.

In the 13th century, Kings Henry III (1216–1272) and Edward I (1272–1307) extended the castle, essentially creating it as it stands today. Henry was disconnected from his barons, and a mutual lack of understanding led to unrest and resentment towards his rule. As a result, he was eager to ensure the Tower of London was a formidable fortification; at the same time Henry was an aesthete and wished to make the castle a comfortable place to live. From 1216 to 1227 nearly £10,000 was spent on the Tower of London; in this period, only the work at Windsor Castle cost more (£15,000). Most of the work was focused on the palatial buildings of the innermost ward. The tradition of whitewashing the White Tower (from which it derives its name) began in 1240.

Later medieval period

During Edward II's reign (1307–1327) there was relatively little activity at the Tower of London. However, it was during this period that the Privy Wardrobe was founded. The institution was based at the Tower and responsible for organising the state's arms. In 1321, Margaret de Clare, Baroness Badlesmere became the first woman imprisoned in the Tower of London after she refused Queen Isabella admittance to Leeds Castle and ordered her archers to target Isabella, killing six of the royal escort. Generally reserved for high-ranking inmates, the Tower was the most important royal prison in the country. However it was not necessarily very secure, and throughout its history people bribed the guards to help them escape. In 1323, Roger Mortimer, Baron Mortimer, was aided in his escape from the Tower by the Sub-Lieutenant of the Tower who let Mortimer's men inside. They hacked a hole in his cell wall and Mortimer escaped to a waiting boat. He fled to France where he encountered Edward's Queen. They began an affair and plotted to overthrow the King.

One of Mortimer's first acts on entering England in 1326 was to capture the Tower and release the prisoners held there. For four years he ruled while Edward III was too young to do so himself; in 1330, Edward and his supporters captured Mortimer and threw him into the Tower. Under Edward III's rule (1312–1377) England experienced renewed success in warfare after his father's reign had put the realm on the backfoot against the Scots and French. Amongst Edward's successes were the battles of Crécy and Poitiers where King John II of France was taken prisoner, and the capture of the King David II of Scotland at Neville's Cross. During this period, the Tower of London held many noble prisoners of war. Edward II had allowed the Tower of London to fall into disrepair, and by the reign of Edward III the castle was an uncomfortable place. The nobility held captive within its walls were unable to engage in activities such as hunting which were permissible at other royal castles used as prisons, for instance Windsor. Edward III ordered that the castle should be renovated.

When Richard II was crowned in 1377, he led a procession from the Tower to Westminster Abbey. This tradition began in at least the early 14th century and lasted until 1660. During the Peasants' Revolt of 1381 the Tower of London was besieged with the King inside. When Richard rode out to meet with Wat Tyler, the rebel leader, a crowd broke into the castle without meeting resistance and looted the Jewel House. The Archbishop of Canterbury, Simon Sudbury, took refuge in St John's Chapel, hoping the mob would respect the sanctuary. However, he was taken away and beheaded on Tower Hill. Six years later there was again civil unrest, and Richard spent Christmas in the security of the Tower rather than Windsor as was more usual. When Henry Bolingbroke returned from exile in 1399, Richard was imprisoned in the White Tower. He abdicated and was replaced on the throne by Bolingbroke, who became King Henry IV. In the 15th century, there was little building work at the Tower of London, yet the castle still remained important as a place of refuge. When supporters of the late Richard II attempted a coup, Henry IV found safety in the Tower of London. During this period, the castle also held many distinguished prisoners. The heir to the Scottish throne, later King James I of Scotland, was kidnapped while journeying to France in 1406 and held in the Tower. The reign of Henry V (1413–1422) renewed England's fortune in the Hundred Years' War against France. As a result of Henry's victories, such as the Battle of Agincourt, many high-status prisoners were held in the Tower of London until they were ransomed.

Changing use

The beginning of the Tudor period marked the start of the decline of the Tower of London's use as a royal residence. As 16th-century chronicler Raphael Holinshed said the Tower became used more as "an armouries and house of munition, and thereunto a place for the safekeeping of offenders than a palace roiall for a king or queen to sojourne in". Henry VII visited the Tower on fourteen occasions between 1485 and 1500, usually staying for less than a week at a time. The Yeoman Warders have been the Royal Bodyguard since at least 1509. In 1517 the Tower fired its cannon at City crowds engaged in the xenophobic Evil May Day riots, in which the properties of foreign residents were looted. It is not thought that any rioters were hurt by the gunfire, which was probably meant merely to intimidate the mob.

During the reign of Henry VIII, the Tower was assessed as needing considerable work on its defences. In 1532, Thomas Cromwell spent £3,593 on repairs and imported nearly 3,000 tons of Caen stone for the work. Even so, this was not sufficient to bring the castle up to the standard of contemporary military fortifications which were designed to withstand powerful artillery. Although the defences were repaired, the palace buildings were left in a state of neglect after Henry's death. Their condition was so poor that they were virtually uninhabitable. From 1547 onwards, the Tower of London was only used as a royal residence when its political and historic symbolism was considered useful, for instance each of Edward VI, Mary I, and Elizabeth I briefly stayed at the Tower before their coronations.

In the 16th century, the Tower acquired an enduring reputation as a grim, forbidding prison. This had not always been the case. As a royal castle, it was used by the monarch to imprison people for various reasons, however these were usually high-status individuals for short periods rather than common citizenry as there were plenty of prisons elsewhere for such people. Contrary to the popular image of the Tower, prisoners were able to make their life easier by purchasing amenities such as better food or tapestries through the Lieutenant of the Tower. As holding prisoners was originally an incidental role of the Tower – as would have been the case for any castle – there was no purpose-built accommodation for prisoners until 1687 when a brick shed, a "Prison for Soldiers", was built to the north-west of the White Tower. The Tower's reputation for torture and imprisonment derives largely from 16th-century religious propagandists and 19th-century romanticists. Although much of the Tower's reputation is exaggerated, the 16th and 17th centuries marked the castle's zenith as a prison, with many religious and political undesirables locked away. The Privy Council had to sanction the use of torture, so it was not often used; between 1540 and 1640, the peak of imprisonment at the Tower, there were 48 recorded cases of the use of torture. The three most common forms used were the infamous rack, the Scavenger's daughter, and manacles. The rack was introduced to England in 1447 by the Duke of Exeter, the Constable of the Tower; consequentially it was also known as the Duke of Exeter's daughter. One of those tortured at the Tower was Guy Fawkes, who was brought there on 6 November 1605; after torture he signed a full confession to the Gunpowder Plot.

Restoration and tourism

The Tower of London has become established as one of the most popular tourist attractions in the country. It has been a tourist attraction since at least the Elizabethan period, when it was one of the sights of London that foreign visitors wrote about. Its most popular attractions were the Royal Menagerie and displays of armour. The Crown Jewels also garner much interest, and have been on public display since 1669. The Tower steadily gained popularity with tourists through the 19th century, despite the opposition of the Duke of Wellington to visitors. Numbers became so high that by 1851 a purpose-built ticket office was erected. By the end of the century, over 500,000 were visiting the castle every year.

Over the 18th and 19th centuries, the palatial buildings were slowly adapted for other uses and demolished. Only the Wakefield and St Thomas's Towers survived. The 18th century marked an increasing interest in England's medieval past. One of the effects was the emergence of Gothic Revival architecture. In the Tower's architecture, this was manifest when the New Horse Armoury was built in 1825 against the south face of the White Tower. It featured elements of Gothic Revival architecture such as battlements. Other buildings were remodelled to match the style and the Waterloo Barracks were described as "castellated Gothic of the 15th century". Between 1845 and 1885 institutions such as the Mint which had inhabited the castle for centuries moved to other sites; many of the post-medieval structures left vacant were demolished. In 1855, the War Office took over responsibility for manufacture and storage of weapons from the Ordnance Office, which was gradually phased out of the castle. At the same time, there was greater interest in the history of the Tower of London.

Public interest was partly fuelled by contemporary writers, of whom the work of William Harrison Ainsworth was particularly influential. In The Tower of London: A Historical Romance he created a vivid image of underground torture chambers and devices for extracting confessions that stuck in the public imagination. Ainsworth also played another role in the Tower's history, as he suggested that Beauchamp Tower should be opened to the public so they could see the inscriptions of 16th- and 17th-century prisoners. Working on the suggestion, Anthony Salvin refurbished the tower and led a further programme for a comprehensive restoration at the behest of Prince Albert. Salvin was succeeded in the work by John Taylor. When a feature did not meet his expectations of medieval architecture Taylor would ruthlessly remove it; as a result, several important buildings within the castle were pulled down and in some cases post-medieval internal decoration removed.

Garrison

The Yeomen Warders provided the permanent garrison of the Tower, but the Constable of the Tower could call upon the men of the Tower Hamlets to supplement them when necessary. The Tower Hamlets, aka Tower Division of Middlesex's Ossulstone Hundred was an area, significantly larger than the modern London Borough of the same name, which owed military service to the Constable in his ex officio role as Lord Lieutenant of the Tower Hamlets.

The earliest surviving reference to the inhabitants of the Tower Hamlets having a duty to provide a guard for the Tower of London is from 1554, during the reign of Mary I, but the relationship is thought to go back much further. Some believe the connection goes back to the time of the Conqueror. The duty is likely to have had its origin in the rights and obligations of the Manor of Stepney which covered most or all of the Hamlets area.

Crown Jewels

The tradition of housing the Crown Jewels in the Tower of London probably dates from the reign of Henry III (1216–1272). The Jewel House was built specifically to house the royal regalia, including jewels, plate, and symbols of royalty such as the crown, sceptre, and sword. When money needed to be raised, the treasure could be pawned by the monarch. The treasure allowed the monarch independence from the aristocracy and consequently was closely guarded. A new position for "keeper of the jewels, armouries and other things" was created, which was well rewarded; in the reign of Edward III (1327–1377) the holder was paid 12d a day. The position grew to include other duties including purchasing royal jewels, gold, and silver, and appointing royal goldsmiths and jewellers.

In 1649, during the English Commonwealth following Charles I's execution, the contents of the Jewel House were disposed of along with other royal properties, as decreed by Cromwell. Metal items were sent to the Mint to be melted down and re-used, and the crowns were "totally broken and defaced".

When the monarchy was restored in 1660, the only surviving items of the coronation regalia were a 12th-century spoon and three ceremonial swords. (Some pieces that had been sold were later returned to the Crown.) Detailed records of old regalia survived, and replacements were made for the coronation of Charles II in 1661 based on drawings from the time of Charles I. For the coronation of Charles II, gems were rented because the treasury could not afford to replace them.

In 1669, the Jewel House was demolished and the Crown Jewels moved into Martin Tower (until 1841). They were displayed here for viewing by the paying public. This was exploited two years later when Colonel Thomas Blood attempted to steal them. Blood and his accomplices bound and gagged the Jewel House keeper. Although they laid their hands on the Imperial State Crown, Sceptre and Orb, they were foiled when the keeper's son turned up unexpectedly and raised the alarm.

Since 1994, the Crown Jewels have been on display in the Jewel House in the Waterloo Block. Some of the pieces were once regularly used by Queen Elizabeth II. The display includes 23,578 gemstones, the 800-year-old Coronation Spoon, St Edward's Crown (traditionally placed on a monarch's head at the moment of crowning) and the Imperial State Crown.

Royal Menagerie

There is evidence that King John (1166–1216) first started keeping wild animals at the Tower. Records of 1210–1212 show payments to lion keepers.

The Royal Menagerie is frequently referenced during the reign of Henry III. Holy Roman Emperor Frederick II presented Henry with three leopards, c. 1235, which were kept in the Tower. In 1252, the sheriffs were ordered to pay fourpence a day towards the upkeep of the King's polar bear, a gift from Haakon IV of Norway in the same year; the bear attracted a great deal of attention from Londoners when it went fishing in the Thames while tied to the land by a chain. In 1254 or 1255, Henry III received an African elephant from Louis IX of France depicted by Matthew Paris in his Chronica Majora. A wooden structure was built to house the elephant, measuring 12.2 m × 6.1 m (40 ft × 20 ft). The animal died in 1258, possibly because it was given red wine, but also perhaps because of the cold climate of England.

In 1288, Edward I added a lion and a lynx and appointed the first official Keeper of the animals.

Edward III added other types of animals, two lions, a leopard and two wildcats. Under subsequent kings, the number of animals grew to include additional cats of various types, jackals, hyenas, and an old brown bear, Max, gifted to Henry VIII by Emperor Maximilian. In 1436, during the time of Henry VI, all the lions died and the employment of Keeper William Kerby was terminated.

Historical records indicate that a semi-circular structure or barbican was built by Edward I in 1277; this area was later named the Lion Tower, to the immediate west of the Middle Tower. Records from 1335 indicate the purchase of a lock and key for the lions and leopards, also suggesting they were located near the western entrance of the Tower. By the 1500s that area was called the Menagerie. Between 1604 and 1606 the Menagerie was extensively refurbished and an exercise yard was created in the moat area beside the Lion Tower. An overhead platform was added for viewing of the lions by the royals, during lion baiting, for example in the time of James I. Reports from 1657 include mention of six lions, increasing to 11 by 1708, in addition to other types of cats, eagles, owls and a jackal.

In folklore

The Tower of London has been represented in popular culture in many ways. As a result of 16th- and 19th-century writers, the Tower has gained a reputation for being a bleak fortress, a place of torture and execution.

One of the earliest traditions associated with the Tower held that it was built by Julius Caesar; the story was popular amongst writers and antiquaries. The earliest recorded attribution of the Tower to the Roman ruler dates to the mid-14th century in a poem by Sir Thomas Gray. The origin of the myth is uncertain, although it may be related to the fact that the Tower was built in the corner of London's Roman walls. Another possibility is that someone misread a passage from Gervase of Tilbury in which he says Caesar built a tower at Odnea in France. Gervase wrote Odnea as Dodres, which is close to the French for London, Londres. Today, the story survives in William Shakespeare's Richard II and Richard III, and as late as the 18th century some still regarded the Tower as built by Caesar.

Anne Boleyn was beheaded in 1536 for treason against Henry VIII; her ghost supposedly haunts the Church of St Peter ad Vincula in the Tower, where she is buried, and has been said to walk around the White Tower carrying her head under her arm. This haunting is commemorated in the 1934 comic song "With Her Head Tucked Underneath Her Arm". Other reported ghosts include Henry VI, Lady Jane Grey, Margaret Pole, and the Princes in the Tower. In January 1816, a sentry on guard outside the Jewel House claimed to have witnessed an apparition of a bear advancing towards him, and reportedly died of fright a few days later. In October 1817, a tubular, glowing apparition was claimed to have been seen in the Jewel House by the Keeper of the Crown Jewels, Edmund Lenthal Swifte. He said that the apparition hovered over the shoulder of his wife, leading her to exclaim: "Oh, Christ! It has seized me!" Other nameless and formless terrors have been reported, more recently, by night staff at the Tower.
