The register’s text, word for word
Description
Located in a land depression at Fort George, a reconstructed fortification complex at Niagara-on-the-Lake, the Powder Magazine is the only remaining original building at the site. The single-storey, symmetrical, stone structure is composed of a main rectangular storage area and a smaller rectangular entry, both topped with copper-clad gable roofs. The building’s thick masonry walls, with simple details around the openings, are reinforced with stone buttresses. The interior features a brick “bomb-proof” arch. The designation is confined to the footprint of the building.
Heritage value
The Powder Magazine was designated a Classified Federal Heritage Building primarily because of its association with the defence of Upper Canada by the British military, and with the 1930s philosophy of restoration. Fort George was built by the British in 1796 for the defence of Upper Canada, after the British garrison was transferred to Newark and Fort Niagara was turned over to the Americans. The fort was attacked and burned by Americans during the War of 1812-14; only the Powder Magazine survives from this period. This historic structure is an important component of the reconstructed fortification complex, developed as a tourist destination in the 1930s under a Depression relief works program. Hence, the Powder Magazine is associated with both the initial growth and defence of Niagara-on-the-Lake, and with its economic development during the 1930s.
The building is a rare surviving example of a British 18th-century powder magazine, and is a well-known landmark.
