In 1759 following the defeat of the French at the Battle of the Plains of Abraham during the Seven Years' War, the commander of the French forces, Chevalier de Lévis, ordered the construction of Fort Jacques-Cartier at the mouth of the Jacques-Cartier River from materials originally destined for the construction of a church. The following year, using the fort as a logistics base, Lévis attempted unsuccessfully with 7,000 men to recapture Quebec City from the British. The British captured the fort in September 1760 and kept a garrison there until 1763 after which they abandoned it. Virtually nothing remains of the fort aside from archaeological remains, which is also situated on private land inaccessible to the public on the 'Plateau Jacques-Cartier' district of the municipality. Close by, is the Allsopp House (late 18th century), an old seigneurial manor named after the Allsopp family, now a private property registered as a historical building.
