in 1848 — At least 40 immigrant vessels waited in quarantine at Grosse Île, Canada, as thousands fleeing Ireland attempted to reach North America during An Gorta Mór.
Located in the St. Lawrence River, downstream from Québec City, Grosse Île became the main quarantine station for immigrants arriving in British North America. During the typhus epidemic of 1847–48, overcrowded “coffin ships” carrying desperate emigrants from Ireland arrived in horrific conditions. Disease spread rapidly aboard the vessels and throughout the quarantine station itself.
Thousands of Irish men, women and children died at sea, in quarantine sheds, or were buried on the island. Grosse Île became one of the great burial places of the Irish diaspora and remains a powerful symbol of suffering, exile and survival.
Today, the island stands as a memorial to those who fled Ireland during An Gorta Mór and helped shape Irish communities across Canada and North America.
