Fort Howe, National historic site in Saint John, Canada

Fort Howe is a national historic site on a rock overlooking the Saint John River harbour, bounded by Magazine, Kitchener, Main and Metcalfe streets. The original fort had a blockhouse on the east of the hill and another enclosed by a palisade on the west. A replica blockhouse now stands about 250 metres northeast of the original structure.

British forces built Fort Howe in 1777 to protect against American privateers during the Revolutionary War. The blockhouse was later reconstructed to stand as a symbol of those defensive efforts.

The fort served as the first civil jail and military command center for the growing settlement of Parrtown, which later became Saint John. These roles made it the hub of early administration and control in the region.

The park is bounded by Magazine Street to the north, Kitchener Street to the east, Main Street to the south and Metcalfe Street to the west. A cairn and commemorative plaque stand west of the park, and the blockhouse replica lies about 250 metres northeast of the original fort site.

Fort Howe was designated a national historic site of Canada on 26 May 1966, and the Historic Sites and Monuments Board of Canada placed a cairn and commemorative plaque west of the park. The site was spared from urban development, though nothing of the original fort remained by 1870.
