Carleton Martello Tower dates from the War of 1812 between Great Britain and the United States. The Tower was part of a defensive system constructed against a landward attack on New Brunswick from the west. The original Tower was typical of a design used during the Napoleaonic Wars. Over one hundred such towers erected in Britain during the period to guard against the possibility of French invasion. Like others of its kind, Carleton Martello was accessible through a doorway in the second story, or barrack floor. The ground floor contained storage space and a powder magazine. The tower’s flat roof was designed to accommodate artillery pieces and was surrounded by a parapet. The key structural feature was a circular brick pillar that supported both the roof and the arched brick ceiling which, along with the thick walls, was designed to absorb artillery fire.
The site is located in West Saint John, New Brunswick.
