About Carleton Martello Tower
Carleton Martello Tower is one of 14 National Historic Sites in Saint John. Construction of Carleton Martello Tower is recorded as 1812–1816.
Located on a high rocky promontory overlooking the harbour, the Carleton Martello Tower is a strongly built, plain, squat, cylindrical stone tower that is two storeys high. The tower’s exterior wall inclines slightly inwards as it rises up to the parapet. Shuttered windows and an arched doorway pierce the wall on the second level. The entrance is accessed by an exterior stairway. A two-storey, concrete command post was added to the top of the tower in 1941. The designation is confined to the footprint of the building.
