''William the Conquerer built the Tower of London for several reasons: to protect London from invasion, to oversee shipping on the Thames, and to scare his subjects. The original tower was built around 1078. It covers 7 hectares on the banks of the Thames River. At various times The Tower has been a mint, a fortress, a vault, a terrible jail and a place of execution! Famous as a showplace for England's elaborate Crown Jewels, the Jewel House includes the largest cut diamond in the world, 530 carats!''
