Tower of London is a historic royal fortress located on the north bank of the River Thames in the City of London. Founded by William the Conqueror in 1066 following the Norman Conquest, the complex began with the construction of the White Tower and expanded over centuries into a fortified palace, prison, armoury and treasury.

Throughout its history, the Tower has served as a royal residence, a place of imprisonment for high-profile figures, the site of executions, and the secure home of the Crown Jewels. Today, it is one of Britain's most significant historic landmarks and a UNESCO World Heritage Site. - AsNotedIn
