Tower Bridge

Tower Bridge is a combined bascule and suspension bridge in central London. Built in 1886, the bridge crosses the River Thames close to the Tower of London.

In 1916, during World War I, the bridge served as an impromptu base of operations for a German spy ring led by the Templar Master Spy. The base was cleared out by the Assassin Lydia Frye, before being occupied by Winston Churchill.
