Fodor's Expert Review Fort William
The irregular heptagon south of the Eden Gardens in the Maidan is surrounded by a moat almost 50 feet wide. Begun in 1757 after Robert Clive's victory at Plassey over Siraj ud-Daula, Fort William was designed to prevent any future attacks. The fort's walls, as well as its barracks, stables, and Church of St. Peter, have survived to this day chiefly because the fort has, in fact, never been attacked. The Indian government still uses the fort, but it's closed to the public.
