NATIONAL HISTORIC SITE
**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 grounds and the Visitor Centre.**
Built for the War of 1812, this circular stone fort played a crucial role in the defence of Saint John and its harbour until 1944. The tower's unique architecture spans 130 years of coastal defence technology.
