Few places in the United Kingdom are as steeped in history, legend, and superstition as the walls of this fortress. This castle is not just about its grand architecture. You can also admire a diamond as big as your fist. The Yeoman Warders, guides proud of their Tudor uniforms, will tell you its chilling story.

Laden with a history as tragic as it is captivating, this royal fortress, bristling with 22 towers, is one of the iconic landmarks of the British capital.
