Tour Tanguy
France
The 186th tallest tower in the world
The Tour Tanguy, Bastille de Quilbignon or Tour de la Motte Tanguy is a medieval tower on a rocky motte beside the Penfeld river in Brest, France. Probably built during the Breton War of Succession, it faces the château de Brest and is now accessed by a road off the square Pierre Péron, at one end of the pont de Recouvrance. It now houses the Museum of Old Brest, a museum with a collection of dioramas that depict the city of Brest on the eve of World War II.
