Thousand-year-old fortress and palace that has served as royal residence, prison, mint, and armoury. Home to the Crown Jewels, Beefeater guards, and centuries of royal intrigue including the imprisonment of Anne Boleyn.
The Tower of London, situated on the north bank of the Thames in the City of London, was founded by William the Conqueror immediately after the Norman Conquest in 1066. The White Tower at the heart of the complex was completed around 1100 under William Rufus and remains one of the best-preserved examples of Norman military architecture in Europe. The fortress expanded steadily over the following two centuries until Henry III and Edward I completed the concentric ring of curtain walls and mural towers that defines the castle's footprint today.
For five centuries the Tower served simultaneously as a royal palace, state prison, mint, public record office, armoury, and menagerie. Monarchs including Henry VI, Anne Boleyn, Catherine Howard, and Lady Jane Grey were imprisoned and executed within its walls. The Bloody Tower, the Traitors' Gate — the Thames-level water entrance through which prisoners arrived by boat — and Tower Green, where executions took place, are among the spaces where this history is most tangibly felt. The Royal Armoury within the White Tower displays one of the world's finest collections of arms and armour, including suits made for Henry VIII at different stages of his life.
The Crown Jewels, held in the Jewel House on the ground floor of the Waterloo Block, are the most visited exhibit. The collection includes the Sovereign's Orb, the Sovereign's Sceptre with Cross set with the 530-carat Cullinan I diamond, and the Imperial State Crown worn at the Coronation. Moving walkways carry visitors past the most precious pieces during peak periods. The ceremony of the Changing of the Guard at the Tower is a separate ritual from the famous evening Ceremony of the Keys, during which the main gates have been locked by the Chief Yeoman Warder every night without exception since at least the 14th century.
The Yeoman Warders — popularly called Beefeaters — have served as the Tower's ceremonial guardians since at least the 15th century and live on site with their families. Their public tours, offered several times daily from the main entrance, are among the best free guided experiences in London. The Tower's six resident ravens, whose presence is said by tradition to ensure the safety of the kingdom, are cared for by the official Ravenmaster, who clips their flight feathers to prevent them from leaving the grounds. The Tower of London is a UNESCO World Heritage Site, designated in 1988.
Why it matters
The Tower of London is one of the most complete medieval royal fortresses in Europe, in continuous use since 1066 as a symbol of royal authority, a place of political imprisonment and execution, and the permanent repository of the English and British Crown Jewels.
