Canada's most visited national historic site, the huge and arguably spooky Citadel is a star-shaped fort atop Halifax's central hill. Construction began in 1749 with the founding of Halifax; this version of the Citadel is the fourth, built from 1818 to 1861. Guided tours explain the fort's shape and history. The grounds inside the fort are open year-round, with free admission when the exhibits are closed.
From November to May, while the grounds remain open, visitor experience services are limited.
