"The Tower of London – Built by William the Conqueror in 1078, the Tower of London was turned into a prison in 1100. Some of its most famous prisoners included King Henry VI, the wives of King Henry VII, Anne Boleyn and Catherine Howard and Sir Thomas More. These days the Tower is a museum rather than a prison. A great way to see some of the grounds is with an entertaining tour hosted by the Yeoman Warders who will frighten and dazzle you with tales of the Towers past."
