Built from 1828 to 1856 by order of the Duke of Wellington, this fort remained intact until the Second World War. It contains a large central parade ground where soldiers attired in 19C uniform perform military drills (from mid-June to mid-August). This sprawling complex houses a visitor centre, barracks, gunpowder magazines and a small museum. An audio-visual display (50min), Tides of History, charts the history of Halifax and its defences. The noon gun is fired on the dot every day.
