On a hill high above Saint John harbour, stands a sentinel to the city’s storied military history.

During the War of 1812, when the US declared war against Great Britain, Royal Engineers built the stone tower to protect New Brunswick's largest and most important port.

Today, you can tour Martello Tower, once used to house magazine and military stores, and as a garrison, prison, and observation post. A film evoking the tower’s history and an award-winning exhibit is on offer in the visitor centre. You can envision soldier life as you tour the tower’s restored barracks room and powder magazine and catch occasional military re-enactments, ghost stories and soldier tales.

Don’t miss the panoramic view from the tower’s observation level, where you can cast a glance at sailboats in Saint John harbour, and dramatic vista to the Bay of Fundy.
