Description: The Tower of London was built by William the Conqueror, following his successful invasion in 1066. His initial structure was added to over the years by the various monarchs until it stood majestic and nearly square with two lines of walls defending the White Tower. The Tower has been host to many famous events - most of them murderous. Perhaps the most infamous of these was the murder of the Princes in the Tower, Edward V and Richard, Duke of York, by Richard III in 1483. It is from this date that the Garden Tower took its present name, The Bloody Tower. Other famous prisoners who were executed on Tower Green include William Wallace, the Scottish rebel made famous by the film Braveheart Anne Boleyn and Catherine Howard, two of Henry VIIIs wives Lady Jane Grey and Sir Walter Raleigh. The Jewel House, which houses the Crown Jewels of the United Kingdom including the 1937 Imperial State Crown, worn by the monarch during the coronation, is also within the confines of the Tower of London. The tower is open daily except Tuesdays.
