12 Best Things to Do in Halifax
"Set in the center of the city is the star-shaped Halifax Citadel which looms over downtown from atop of its prominent hilltop. Such is its strategic position that four forts have been built in the same spot since 1749 with the current citadel having been completed in 1856. Besides wandering around the grounds and fortifications of the National Historic Site, visitors can also stop by its on-site Army Museum."
