Perched high on a rocky cliff 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. Visitors marvel at the spectacular city and harbour views while exploring the award-winning interactive exhibits in the Visitor Centre. The tower was the heart of Saint John defences until 1944.

The martello 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 Visitor Centre and grounds.
