Three forts were built near this site between 1865 and 1871 in response to the border tensions during the American Civil War. As a strategic part of Québec's fortification system, they were to defend the city and its harbour from a possible invasion from Maine. Never completely armed or garrisoned, they were virtually abandoned following the signing of the Treaty of Washington by Great Britain and the United States in 1871. The design of the three forts, of which only Fort No. 1 remains, illustrates a transition from the principles of classical fortification to the military practices of the mid-nineteenth century.

Description of Historic Place

Lévis Forts National Historic Site of Canada consists of the above and below-ground remains of three 19th-century stone defensive works located on a height of land on the south bank of the St. Lawrence River at Lévis, Québec. The three forts, arranged in a linear pattern, are each approximately 1800 metres apart. The site includes the extant fortification of Fort No. 1, the archaeological remains of Forts No. 2 and 3 as well as evidence of roads leading between the forts, and camps used by construction teams. Official recognition refers to an arced strip of land about 300 metres in width and 4.8 kilometres in length.

Heritage Value

Lévis Forts was designated a national historic site of Canada in 1920 because: they are an integral part of the fortifications of Québec; they were of strategic importance in the defensive system of Québec.

The decision to build three forts at Lévis to complete Québec’s system of defence was made by the British during the American Civil War under the threat of an invasion by Union soldiers. The British sent William Drummond Jervois to Québec to design improvements to the defensive fortifications at Lévis in order to protect the soldiers stationed there. The construction of the three forts began in 1865, under the direction of the Royal Engineers, and Fort No. 1 was completed in 1872. In addition to the forts, work included the building of a construction camp of some 20 buildings, a dock and a communications network along the St. Lawrence River. Innovative methods were tried and proven in the design, surveying and construction of the Lévis Forts. Steam-powered equipment was used to make concrete faced with stone and the escarpment of Fort No. 1 was constructed of new types of concrete poured in stone frames. No garrisons ever occupied the forts however, because the signing of the Washington Treaty in 1871 eliminated the fear of further clashes between the British and the Americans.
