This historic clock, looking out over Halifax Harbour, first began keeping time in 1803, for the British Army and Royal Navy garrison posted to protect this major seaport. Its creation was initiated by Prince Edward, Duke of Kent, and the mechanism, which is still operating after two centuries, was constructed by House of Vulliamy - Royal clockmakers in London. It is a three-tiered octagon, with four-sided clock faces, and sits atop a one-storey clapboard building (which I cropped out of the shot) where the caretaker once lived. The pendulum itself is 13 feet long and the clock is wound twice weekly. It has become an iconic symbol of Halifax and its resonant chimes ring out across the city on the hour and quarter-hour. The clock is part of the Halifax Citadel National Historic Site operated by Parks Canada.
