Encountering this squat, round structure built of stone transports you back over two centuries to an era of military clashes between British and French forces. Almost three times as wide as it is high, Prince of Wales Tower is the oldest Martello tower in North America. Its 8-foot thick walls once protected British sea batteries from a French landward attack as part of the formidable coastal defence network, which included nearby Halifax Citadel. While other locations within the defence complex were in use until after World War II, changing military technology rendered the Prince of Wales Tower obsolete by the time the surrounding land was leased to the city for a park in 1866. Standing before this the tower site located in Point Pleasant Park, you gain a deeper appreciation for the strategy the British employed to defend the area from the French.
