Prisoners & escapes · Everyday life at the Tower

The Tower's last prisoners

The first prisoner escaped down a rope in 1101. The last man executed here was shot in a chair in 1941. In between the Tower went from royal castle to something close to a museum, and then, briefly, back.

The Tower was never built as a prison. It became one because it was the strongest building in the kingdom and belonged to the king, and for eight hundred years anyone the crown wanted kept safe, or kept quiet, could be put inside it. The list runs from kings of Scotland and France to bishops, queens, poets, forgers and, at the very end, spies.

The first, and the first to leave

The first recorded prisoner was Ranulf Flambard, Bishop of Durham, the financial enforcer of William Rufus, locked up in the White Tower in 1100 by the new king, Henry I, who needed a scapegoat. In February 1101 a cask of wine was delivered to him. Flambard shared it generously with his guards, and when they were asleep he took the rope that had come coiled inside the cask, tied it to a window column and let himself down the outside of the keep. His friends were waiting with horses. He got to Normandy and was eventually reconciled with the king. He was the Tower’s first prisoner and its first escapee, and he set a standard for ingenuity that nobody quite matched until the Countess of Nithsdale six centuries later.

The long middle

Most of the famous names belong to the Tudor and Stuart centuries, when the Tower was the state prison and Tower Hill the state scaffold. What is less well known is how the prison faded. From the eighteenth century the Tower was increasingly a garrison, an arsenal, a mint and a public attraction, and prisoners became rare. The last execution on Tower Hill was the beheading of the Jacobite Lord Lovat in 1747. By Queen Victoria’s reign the prison rooms were curiosities shown to visitors.

The two world wars brought it back. In the First World War eleven German spies were shot at the Tower after courts-martial, in the rifle range in the outer ward. And in 1939 the fortress closed its gates to the public, its armour was packed away, its Crown Jewels sent secretly to Windsor, and the buildings around the White Tower became a Prisoner of War Collection Centre where captured enemy personnel were held and questioned before being sent on to camps. Wounded prisoners went to the Old Hospital Block; others were held in the New Armouries, where the café is now. The moat was dug up for vegetables. On 5 October 1940 a bomb blew apart the North Bastion and narrowly missed the White Tower; a Yeoman Warder and a woman resident were killed in the raids.

May 1941: the deputy Führer

On the night of 10 May 1941 Rudolf Hess, Hitler’s deputy, flew a Messerschmitt alone to Scotland and parachuted into a field, apparently hoping to negotiate peace with people he imagined were willing. He was brought south and, for four days from 17 May, held in the Queen’s House on Tower Green, the same Lieutenant’s Lodgings where Guy Fawkes had been questioned and Lord Nithsdale had put on a dress. He was then moved to a series of safer houses and spent the rest of his life in custody.

August 1941: the last

Josef Jakobs was a German soldier, a dentist by training, who was dropped by parachute over Huntingdonshire on the last night of January 1941 with a radio, forged papers and a ration book. He broke his ankle landing, lay in a field all night, and in the morning fired his pistol to attract attention. Farm workers found him. He was tried by court-martial as an enemy combatant, not in a civilian court, which is why his sentence was carried out at the Tower rather than in a prison. On the morning of 15 August 1941 he was taken to the miniature rifle range in the outer ward, seated in a chair because of his ankle, and shot by a firing squad of eight Scots Guards. He is buried in an unmarked grave in Kensal Green. He was the last person executed at the Tower of London.

A small plaque near the site records his name and the date. It is not on any tour, and most visitors walk past it. It is the end of a story that began with a bishop and a rope.

What to look for when you visit

  • The Bell Tower and the Beauchamp Tower on the west side: Tudor prison rooms that were still in use, on and off, into the twentieth century.
  • The Queen's House on Tower Green, where Hess was held in May 1941 and where Guy Fawkes had been questioned in 1605.
  • The east side of the outer ward, where the wartime rifle range stood; the plaque to Jakobs is on that side of the fortress.
  • The moat: an allotment during the war, an air-raid target, and in 2022 a wildflower meadow.

What we know, and what remains uncertain

Fact: supported by the cited sources. Disputed: historians disagree or the evidence is incomplete. Legend: a good story with no reliable source.

  • Fact

    Ranulf Flambard escaped from the White Tower in 1101 using a rope smuggled in with wine. Josef Jakobs was executed by firing squad at the Tower on 15 August 1941, the last person executed there.

  • Fact

    The Tower closed to the public at the outbreak of war in September 1939; a Prisoner of War Collection Centre operated here from 3 September 1939; the Crown Jewels were removed to Windsor; the North Bastion was destroyed by a bomb on 5 October 1940.

  • Fact

    Rudolf Hess was held at the Tower for four days in May 1941 after flying to Scotland.

  • Disputed

    Whether the Kray twins, held briefly in 1952 for failing to report for national service, count as the Tower's 'last prisoners'. They were detained by the Royal Fusiliers, whose depot was here, rather than as state prisoners, and this site does not include them in the count.

Getting there inside the Tower

The outer ward and moat edge are level. The wall walk and its towers are stairs only. The Queen's House is not open.

Physical access at the Tower is described by Historic Royal Palaces; this describes the site, not this website's own accessibility.

The White Tower and the Line of Kings

The keep that gives the whole fortress its name has been standing for 950 years, and it has held the world's oldest museum display for more than three hundred of them.
