Welcome to one of the most famous and imposing fortresses on the planet. You are standing before the Tower of London, a site that has anchored the British capital for nearly one thousand years.[1] This massive twelve acre complex, located right on the north bank of the River Thames, was designated as a World Heritage Site by the United Nations Educational, Scientific and Cultural Organization for its global significance. It was founded in late ten sixty-six by William the Conqueror, who had just arrived from Normandy and needed a way to control and intimidate the local Londoners. As you look at the thick stone walls, try to imagine this place in the eleven hundreds when it was the tallest and most terrifying building in the city. Over the centuries, it evolved from a simple wooden fort into a sprawling royal residence, a high-security prison, and a sanctuary for the nation's greatest treasures. Today, it stands as a living museum where ancient rituals are still performed alongside modern-day tourism. Take a moment to breathe in the history; you are about to walk through the gates where kings, queens, and traitors once trod.
