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, 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". 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. 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. – 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. 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. The
Anglo-Saxon Chronicle records that in 1097 King
William II ordered a wall to be built around the Tower of London; it was probably built from stone and likely replaced the timber palisade that arced around the north and west sides of the castle, between the
Roman wall (to the east) and the Thames (to the south). The Norman Conquest of London manifested itself not only with a new ruling class, but in the way the city was structured. Land was confiscated and redistributed amongst the Normans, who also brought over hundreds of Jews, for financial reasons. The Jews used the Tower as a retreat, when threatened by anti-Jewish violence. When he tried the same ploy again, this time holding secret talks with Matilda, Stephen had him arrested, forced him to cede control of his castles, and replaced him with one of his most loyal supporters. Until then the position had been hereditary, originally held by
Geoffrey de Mandeville, but the position's authority was such that from then on it remained in the hands of an appointee of the monarch. The position was usually given to someone of great importance, who might not always be at the castle due to other duties. Although the Constable was still responsible for maintaining the castle and its garrison, from an early stage he had a subordinate to help with this duty: the Lieutenant of the Tower.
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. 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. 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. Beginning around 1238, the castle was expanded to the east, north, and north-west. The work lasted through the reign of Henry III and into that of Edward I, interrupted occasionally by civil unrest. New creations included a new defensive perimeter, studded with towers, while on the west, north, and east sides, where the wall was not defended by the river, a defensive ditch was dug. The eastern extension took the castle beyond the bounds of the old Roman settlement, marked by the city wall which had been incorporated into the castle's defences. The expansion caused disruption locally and £166 was paid to
St Katherine's Hospital and the prior of
Holy Trinity in compensation. Henry III often held court at the Tower of London, and held parliament there on at least two occasions (1236 and 1261) when he felt that the barons were becoming dangerously unruly. In 1258, the discontented barons, led by
Simon de Montfort, forced the King to agree to reforms including the holding of regular parliaments. Relinquishing the Tower of London was among the conditions. Henry III resented losing power and sought permission from the pope to break his oath. With the backing of mercenaries, Henry installed himself in the Tower in 1261. While negotiations continued with the barons, the King ensconced himself in the castle, although no army moved to take it. A truce was agreed with the condition that the King hand over control of the Tower once again. Henry won a significant victory at the
Battle of Evesham in 1265, allowing him to regain control of the country and the Tower of London. Cardinal
Ottobuon came to England to excommunicate those who were still rebellious; the act was deeply unpopular and the situation was exacerbated when the cardinal was granted custody of the Tower.
Gilbert de Clare, 6th Earl of Hertford, marched on London in April 1267 and laid siege to the castle, declaring that custody of the Tower was "not a post to be trusted in the hands of a foreigner, much less of an ecclesiastic". Despite a large army and siege engines, Gilbert de Clare was unable to take the castle. The Earl retreated, allowing the King control of the capital, and the Tower experienced peace for the rest of Henry's reign. Although he was rarely in London, Edward I undertook an expensive remodelling of the Tower, costing £21,000 between 1275 and 1285, over double that spent on the castle during the whole of Henry III's reign. Edward I was a seasoned castle builder, and used his experience of siege warfare during the
crusades to bring innovations to castle building. At the Tower of London, Edward filled in the moat dug by Henry III and built a new curtain wall along its line, creating a new enclosure. A new moat was created in front of the new curtain wall. The western part of Henry III's curtain wall was rebuilt, with Beauchamp Tower replacing the castle's old gatehouse. A new entrance was created, with elaborate defences including two gatehouses and a
barbican. In an effort to make the castle self-sufficient, Edward I also added two
watermills. Six hundred Jews were imprisoned in the Tower of London in 1278, charged with
coin clipping. In 1279, the country's numerous mints were unified under a single system whereby control was centralised to the mint within the Tower of London, while mints outside of London were reduced, with only a few local and
episcopal mints continuing to operate. During this period, many Jews were imprisoned at the Tower before
Edward I's
edict of expulsion in 1290.
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 a state of disrepair, , the nephew of the King of France, was held in the Tower during the Hundred Years' War. This late 15th-century image is the earliest surviving non-schematic picture of the Tower of London. It shows the White Tower, the water-gate, and
Old London Bridge in the background. 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. Much of the latter half of the 15th century was occupied by the
Wars of the Roses between the claimants to the throne, the houses of
Lancaster and
York. The castle was
once again besieged in 1460, this time by a
Yorkist force. The Tower was damaged by artillery fire but only surrendered when
Henry VI was captured at the
Battle of Northampton. With the help of
Richard Neville, 16th Earl of Warwick (nicknamed "the Kingmaker") Henry recaptured the throne for a short time in 1470. However,
Edward IV soon regained control and Henry VI was imprisoned in the Tower of London, where he was probably murdered.
Edward V's uncle
Richard, Duke of Gloucester was declared
Lord Protector while the prince was too young to rule. Traditional accounts have held that the 12-year-old Edward was confined to the Tower of London along with his younger brother
Richard. The Duke of Gloucester was proclaimed King Richard III in June. The princes were last seen in public in June 1483; Opposition to Richard escalated until he was defeated at the
Battle of Bosworth Field in 1485 by the Lancastrian
Henry Tudor, who ascended to the throne as Henry VII.
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. 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. 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 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. The Tower was often a safer place than other prisons in London such as the
Fleet, where disease was rife. High-status prisoners could live in conditions comparable to those they might expect outside; one such example was that while
Walter Raleigh was held in the Tower his rooms were altered to accommodate his family, including his son who was born there in 1605. Before the 20th century, there had been seven executions within the castle on
Tower Green; as was the case with
Lady Jane Grey, this was reserved for prisoners for whom public execution was considered dangerous. Queen Mary I imprisoned her sister Elizabeth, later Queen Elizabeth I, in the Tower under suspicion of causing rebellion as Sir
Thomas Wyatt had led a revolt against Mary in Elizabeth's name. to the north of the Tower of London. Over a period of 400 years, 112 people were executed on the hill. As there was no standing army before 1661, the importance of the royal armoury at the Tower of London was that it provided a professional basis for procuring supplies and equipment in times of war. The two bodies were resident at the Tower from at least 1454, and by the 16th century they had moved to a position in the inner ward. The
Board of Ordnance (successor to these Offices) had its headquarters in the White Tower and used surrounding buildings for storage. In 1855 the Board was abolished; its successor (the
Military Store Department of the
War Office) was also based there until 1869, after which its headquarters staff were relocated to the
Royal Arsenal in
Woolwich (where the recently closed
Woolwich Dockyard was converted into a vast ordnance store). Political tensions between
Charles I and Parliament in the second quarter of the 17th century led to an attempt by forces loyal to the King to secure the Tower and its valuable contents, including money and munitions. London's
Trained Bands, a militia force, were moved into the castle in 1640. Plans for defence were drawn up and gun platforms were built, readying the Tower for war. The preparations were never put to the test. In 1642, Charles I attempted to arrest five members of parliament. When this failed he fled the city, and Parliament retaliated by removing Sir
John Byron, the Lieutenant of the Tower. The Trained Bands had switched sides, and now supported Parliament; together with the London citizenry, they blockaded the Tower. With permission from the King, Byron relinquished control of the Tower. Parliament replaced Byron with a man of their own choosing, Sir
John Conyers. By the time the
English Civil War broke out in November 1642, the Tower of London was already in Parliament's control. The last monarch to uphold the tradition of taking a procession from the Tower to Westminster to be crowned was
Charles II in 1661. At the time, the castle's accommodation was in such poor condition that he did not stay there the night before his coronation. Under the
Stuart kings the Tower's buildings were remodelled, mostly under the auspices of the Office of Ordnance. Just over £4,000 was spent in 1663 on building a new storehouse, now known as the New Armouries in the inner ward. When the
Great Fire of London broke out on 2 September 1666,
Samuel Pepys ascended the Tower to view the early progress of the fire, which he reported, collecting further reports from witnesses on the way, to Charles II and his brother, the
Duke of York at
Whitehall Palace. Two days later (Tuesday 4 September), through the day, the flames began to move eastward from the neighbourhood of
Pudding Lane, straight against the prevailing east wind and towards the Tower, potentially threatening its gunpowder stores. The garrison at the Tower took matters into their own hands after waiting all day for requested help from the official firemen supervised by the Duke of York, who were busy in the west, by blowing up houses on a large scale in the vicinity to create firebreaks, halting the advance of the fire. When the
Hanoverian dynasty ascended the throne, their situation was uncertain and with a possible Scottish rebellion in mind, the Tower of London was repaired. Most of the work in this period (1750 to 1770) was done by the King's Master Mason,
John Deval. Gun platforms added under the Stuarts had decayed. The number of guns at the Tower was reduced from 118 to 45, and one contemporary commentator noted that the castle "would not hold out four and twenty hours against an army prepared for a siege". For the most part, the 18th-century work on the defences was spasmodic and piecemeal, although a new gateway in the southern curtain wall permitting access from the wharf to the outer ward was added in 1774. The moat surrounding the castle had become silted over the centuries since it was created despite attempts at clearing it. It was still an integral part of the castle's defences, so in 1830 the Constable of the Tower, the
Duke of Wellington, ordered a large-scale clearance of several feet of silt. However this did not prevent an outbreak of disease in the garrison in 1841 caused by poor water supply, resulting in several deaths. To prevent the festering ditch posing further health problems, it was ordered that the moat should be drained and filled with earth. The work began in 1843 and was mostly complete two years later. The construction of the Waterloo Barracks in the inner ward began in 1845, when the Duke of Wellington laid the foundation stone. The building could accommodate 1,000 men; at the same time, separate quarters for the officers were built to the north-east of the White Tower. The building is now the headquarters of the
Royal Regiment of Fusiliers. The popularity of the
Chartist movement between 1828 and 1858 led to a desire to refortify the Tower of London in the event of civil unrest. It was the last major programme of fortification at the castle. Most of the surviving installations for the use of artillery and firearms date from this period. During the
First World War, eleven men were tried in private and shot by firing squad at the Tower for espionage. During the
Second World War, the Tower was once again used to hold prisoners of war. One such person was
Rudolf Hess,
Adolf Hitler's deputy, albeit just for four days in 1941. He was the last state prisoner to be held at the castle. The last person to be executed at the Tower was German spy
Josef Jakobs who was shot on 15 August 1941. The executions for espionage during the wars took place in a prefabricated miniature
rifle range which stood in the outer ward and was demolished in 1969. The Second World War also saw the last use of the Tower as a fortification. In the event of a
German invasion, the Tower, together with the Royal Mint and nearby warehouses, was to have formed one of three "keeps" or complexes of defended buildings which formed the last-ditch defences of the capital. ==Restoration and tourism==
