Since 1100, it’s held the likes of Anne Boleyn (beheaded in 1536) and the Kray twins (the last, in 1952).
Spread over almost five hectares in central London, the Tower was originally a castle. It’s been an armoury, menagerie and the Royal Mint but, most infamously, a prison. Since 1100, it’s held the likes of Anne Boleyn (beheaded in 1536) and the Kray twins (the last, in 1952). Visitors beware: it is, of course, haunted.
