Statement of Significance

Description of Historic Place

Building 42, also known as the Former Expense Magazine, is located on the ramparts of the Dalhousie Bastion above the casemates and is partially sunk within the ramparts across the line of the parapet of the Québec Citadel National Historic Site of Canada. Not easily visible, it is a small, rectangular, one-storey building built of masonry with a low, sloping copper roof that slopes gently down to the back. It is constructed of regular coursed limestone with an arched entry door. The designation is confined to the footprint of the building.

Heritage Value

Building 42 is a Recognized Federal Heritage Building because of its historical associations, and its architectural and environmental values.

Historical Value
Building 42 is associated with the defense of British North America during the final years of construction of the Citadelle (1839 -1857) against the threat posed by the United States. The building was used to store a small quantity of ammunition gunpowder for immediate use. It is also part of the historic district of Old-Québec, which was created in 1963 and declared a World Heritage Site by UNESCO in 1985.

Architectural Value
Building 42 is valued for its good aesthetics. It is a utilitarian military building of austere appearance. Well integrated into the other works of the citadel, it enhanced the defense of the fortress. Good functional qualities are evidenced in its simple design. The stonework and copper roof display good craftsmanship.

Environmental Value
Building 42 reinforces the historic character of its military site within the Citadelle of Québec, and together with the associated adjacent buildings is a well-known local landmark.
