About Caponier
The federal government recognizes Caponier for its heritage, one of 3 such buildings in Prescott. Caponier dates from 1839–1840. The register names Royal Engineers as its architect.
The Caponier at Fort Wellington is located at the Fort Wellington National Historic Site of Canada, which overlooks the St. Lawrence River. Jutting out of the earthworks into the south ditch, the Caponier is a simple defensive structure with low masonry walls laid in a U-shaped footprint. Regularly placed musket loopholes pierce the thick walls and contribute to its military appearance. The curved southern end of the structure is followed by the elegant curve of the pitched roof. The northern end of the structure disappears into the earthworks, where it narrows to a tunnel leading under the earthen mound and out into the fort interior. The designation is confined to the footprint of the building.
