Tower of London
The Tower of London is perhaps the single most famous London landmark, best known for its history as a jail. Today, the tower, which dates to 1078, is one of London’s most popular tourist attractions and is home to the Crown Jewels. The tower, which sits on the north bank of the River Thames, has been besieged at various times and controlling the edifice has been critical to control of England. Its peak use as a prison was the 16th and 17th centuries. Among the many prominent people “sent to the Tower” are Anne Boleyn, Sir Walter Raleigh and Elizabeth Throckmorton.
