Carleton Martello Tower National Historic Site

The Tower is currently undergoing vital restoration work. Although visitors are not able to enter the tower during this time, we encourage them to explore and enjoy the grounds and the Visitor Centre.

Overlooking Saint John, the British-built Carleton Martello Tower dates from the War of 1812 and played a pivotal role in conflicts leading up to World War II. The tower was the heart of Saint John defenses until 1944.
