Statement of Significance

Description of Historic Place

The Cap Redoubt of the Quebec Citadel National Historic Site of Canada sits on a manicured landscape with lawns and paved paths leading to the entrance, with spectacular views of the city and the St. Lawrence River. It is a small, compact, one-storey, stone masonry structure with a sloping wall facing northeast and a flat roof surmounted by a parapet. The designation is confined to the footprint of the building.

Heritage Value

The Cap Redoubt is a Classified Federal Heritage Building because of its historical associations, and its architectural and environmental value.

Historical Value
The Cap Redoubt building serves as one of the best illustrations of the period from the 17th to 19th centuries when Québec was a fortified town and it is one of the best examples of the influence that the presence of military forces and increasing activities related to defensive works played on socioeconomic life during this period. The walls played a major role in the city’s future development, as they often limited expansion and influenced growth patterns.

Architectural Value
The Cap Redoubt is a very good example of a defensive military structure that projects an image of strength and is characterized by its irregular shape, its sloping wall facing northeast, and almost blank walls. The small defensive structure is one of the rare vestiges of the original Québec fortifications, and the oldest military extant, which was erected during the French Regime in Canada. It is also among the oldest military buildings in Canada.

The Environmental Value
Standing on the King’s Bastion in the Citadel in the City of Québec, the Cap Redoubt is located on landscaped grounds near the Governor General’s summer residence in the Citadel, one of the most popular tourist attractions in the City of Québec. In 1986, the Historic District of Québec received world recognition when UNESCO declared it a World Heritage Site as the only fortified city in North America; the Redoubt as a key component of those fortifications reinforces the historical military character of the World Heritage and National Historic Site.
