Grosse Île and the Irish Memorial National Historic Site
Grosse Île is an island in the St. Lawrence Estuary, 46 km downstream from Quebec City. It is 2.9 km long and 1 km wide and consists of a wooded Appalachian ridge surrounded by a coastline of coves and capes. It is one of the 21 islands composing the Isle-aux-Grues archipelago. It has also been known as Île de Grâce and Quarantine Island. From 1832 to 1937, it was used as a quarantine station for the port of Quebec City. Over this century of activity, more than 4 million immigrants passed through this station, including nearly 90,000 during the “black year” of 1847. Closely tied to memories of Irish immigration to Canada, Grosse Île is a Canadian national historic site, administered by Parks Canada and open to the public.
