The Tower of London
Her Majesty's Royal Palace and Fortress, more commonly known as the Tower of London, is a historic castle on the north bank of the River Thames in central London, England. It lies within the London Borough of Tower Hamlets, separated from the eastern edge of the City of London by the open space known as Tower Hill. It was founded towards the end of 1066 as part of the Norman Conquest of England. The White Tower, which gives the entire castle its name, was built by William the Conqueror in 1078, and was a resented symbol of oppression, inflicted upon London by the new ruling elite. The castle was used as a prison since at least 1100, although that was not its primary purpose. A grand palace early in its history, it served as a royal residence. As a whole, the Tower is a complex of several buildings set within two concentric rings of defensive walls and a moat. There were several phases of expansion, mainly under Kings Richard the Lionheart, Henry III, and Edward I in the 12th and 13th centuries. The general layout established by the late 13th century remains despite later activity on the site.
In the late 15th century the castle was the prison of the Princes in the Tower. Under the Tudors, the Tower became used less as a royal residence, and despite attempts to refortify and repair the castle its defences lagged behind developments to deal with artillery. The peak period of the castle's use as a prison was the 16th and 17th centuries, when many figures fallen into disgrace, such as Elizabeth I before she became queen, were held within its walls. This use has led to the phrase "sent to the Tower". Despite its enduring reputation as a place of torture and death, popularised by 16th-century religious propagandists and 19th-century writers, only seven people were executed within the Tower before the World Wars of the 20th century. Executions were more commonly held on the notorious Tower Hill to the north of the castle, with 112 occurring there over a 400-year period. In the latter half of the 19th century, institutions such as the Royal Mint moved out of the castle to other locations, leaving many buildings empty.
In the First and Second World Wars, the Tower was again used as a prison. 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 14 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. After the wars, damage caused during the Blitz was repaired and the castle reopened to the public. Today the Tower of London is one of the country's most popular tourist attractions. It is cared for by the charity Historic Royal Palaces and is protected as a World Heritage Site.
