Statement of Significance

Description of Historic Place

Building 30, also known as the old Latrines and old Battery Magazine, is located within the Quebec Citadel National Historic Site of Canada, inside the King’s Bastion. Designed as latrines for the nearby Prison, this little building also served as a munitions magazine with a dividing wall separating the two functions. The small, rectangular single-storey building has a pavilion roof clad in painted pinched sheet metal. The designation is confined to the footprint of the building.

Heritage Value

Building 30 is a Recognized Federal Heritage Building because of its historical associations, and its architectural and environmental value.

Historical Value
Building 30 is associated with the defence of British North America during the period when construction of the Citadel was gradually completed (1839-1857). This building is more particularly associated with the first phase of this period (1839-1842), which was marked by tensions created by the 1837 Rebellion, leading to upgrading of the fortification’s defensive system.

Architectural Value
Building 30 demonstrates good aesthetic design in its utilitarian plan. The design demonstrates a certain elegance as seen in its stone arches over the doors. The building demonstrates a very good functional design that supported a dual function: latrines and a small battery magazine. The building was built with massive masonry walls, a transverse divider and a vaulted interior, to minimize damage in the event of an explosion. Very good craftsmanship and materials is therefore clearly noted in this solid building.

The Environmental Value
Building 30 reinforces the historical military character of the Citadel, and is part of the King’s Bastion. Together with the associated adjacent buildings, it is a well-known local landmark.
