About Caponier
The federal government recognizes Caponier for its heritage, one of 55 such buildings in Kingston. By its record, Caponier was built in 1832–1838. The register names Lt.-Colonel Gustavus Nicolls, Corps of Royal Engineers as its architect.
Integral to Fort Henry, which overlooks Lake Ontario, the Caponier of the Fort Henry National Historic Site of Canada is a defensive structure centred in the fort’s main ditch. It is a simple, symmetrical projection from the redoubt’s north face with loopholes at ground level. Smooth limestone walls and a stone roof sit over a bomb-proof vault. The designation is confined to the footprint of the building.
