The Tower of London, officially Her Majesty's Royal Palace and Fortress of the Tower of London, is a historic castle on the north bank of the Thames in central London. Founded in 1066 by William the Conqueror as part of the Norman Conquest of England, it has served as a royal residence, prison, place of execution, armory, treasury, zoo, and — since 1303 — the home of the Crown Jewels of England.

Introduction

The complex covers 12 acres and consists of multiple buildings set within two concentric rings of defensive walls and a moat. The White Tower, the central keep built by William the Conqueror, is one of the finest examples of Norman military architecture in existence. The Tower of London was designated a UNESCO World Heritage Site in 1988 and attracts nearly 3 million visitors annually.

Architecture & Fortification

  • Founded: 1066 by William the Conqueror
  • Central Keep: The White Tower (completed c. 1100)
  • Total Area: 12 acres (4.9 hectares)
  • Walls: Two concentric rings with 21 towers

The White Tower, the oldest part of the complex, was built of Caen stone imported from Normandy and stands 27 meters tall. Its walls are up to 4.6 meters thick at the base, a testament to the defensive paranoia of the Norman conquerors in a hostile land. Over the following centuries, successive monarchs expanded the complex by adding curtain walls, towers, a moat, and numerous buildings within the walls.

The current layout dates largely from the reign of Edward I (1272–1307), who built the outer curtain wall and filled the moat, creating the concentric castle design that made the Tower one of the most formidable fortresses in medieval Europe. The Traitors' Gate, through which prisoners arrived by boat from the Thames, remains one of the most evocative entrances in any castle in the world.

The Crown Jewels

  • Location: Jewel House within the Tower
  • Collection: Over 100 objects including crowns, scepters, and orbs
  • Most Famous: Imperial State Crown with 2,868 diamonds
  • Koh-i-Noor: 105.6-carat diamond in the Queen Mother's Crown

The Crown Jewels of England, housed in the Jewel House within the Tower, constitute one of the most valuable collections of gemstones and regalia in the world. The collection includes the Imperial State Crown, set with 2,868 diamonds including the 317-carat Cullinan II diamond; the Sovereign's Orb; and the Sovereign's Sceptre, containing the 530-carat Cullinan I — the largest clear-cut diamond in the world.

The jewels are used in coronation ceremonies and state occasions. They have been kept at the Tower since 1303, when a theft from Westminster Abbey prompted their relocation to the better-defended fortress. Colonel Thomas Blood famously attempted to steal them in 1671, getting as far as flattening the crown with a mallet before being apprehended. Remarkably, King Charles II pardoned Blood and granted him lands in Ireland.

Prisoners & Executions

  • Famous Prisoners: Anne Boleyn, Sir Walter Raleigh, Guy Fawkes, Rudolf Hess
  • Executions: Seven people executed within the walls (Tower Green)
  • Last Prisoner: Rudolf Hess (1941)

The Tower's reputation as a place of imprisonment and death, while somewhat exaggerated by popular culture, is grounded in real history. Among its most notable prisoners were Anne Boleyn (executed 1536), Lady Jane Grey (executed 1554), Sir Walter Raleigh (imprisoned 1603–1616), and Guy Fawkes (tortured 1605). Only seven people were executed privately on Tower Green within the walls; most public executions took place on Tower Hill outside.

The last person to be held at the Tower was Rudolf Hess, Adolf Hitler's deputy, who was briefly imprisoned there in 1941 after his bizarre solo flight to Scotland. The last executions at the Tower took place during World War II, when 12 men were shot for espionage between 1914 and 1941. The Tower's dungeon and torture instrument displays continue to fascinate visitors.

The Ravens & Traditions

  • Ravens: At least 6 must be kept at all times
  • Legend: If the ravens leave, the Tower and kingdom will fall
  • Yeoman Warders: 37 ceremonial guards (Beefeaters)
  • Ceremony of the Keys: Nightly locking ritual since the 14th century

Legend holds that if the ravens ever leave the Tower, the Crown will fall and Britain with it. Charles II is said to have decreed that at least six ravens must be kept at the Tower at all times, and they are still maintained by a dedicated Ravenmaster. The current ravens have one wing clipped to prevent them from flying away, and they are cared for with a diet of raw meat and biscuits.

The Yeoman Warders, popularly known as Beefeaters, have guarded the Tower since the Tudor period. They serve as both ceremonial guards and tour guides, and all are retired senior non-commissioned officers from the British Armed Forces with at least 22 years of service. The nightly Ceremony of the Keys, in which the Tower is locked for the night, has been performed without interruption for over 700 years.
