Halifax Citadel National Historic Site
Completed in 1856, the present Citadel is the fourth in a series of forts since 1749 to occupy the hill overlooking the harbour. Although never attacked, the fort was occupied by the British army until 1906 and by Canadian forces during the world wars. Now operated by Parks Canada, the Citadel is one of Canada’s most visited National Historic Sites. Buildings open daily until October 31. Grounds open year-round (no services in off-season). Average duration of visit: three hours.
