Built by the British army in 1797, the Prince of Wales Tower was one of numerous fortifications that defended Halifax from enemy attack. The tower’s main purpose was to protect the landward approaches to the gun batteries located along the shores of what is now Point Pleasant Park. Here the hunter, Orion, trails above the tower.
