Old Longueuil

Old Longueuil is a heritage site stretching along the Saint Lawrence River with some 450 historical buildings from different periods. The Co-Cathedral of Saint-Antoine-de-Padoue and Saint Mark's Anglican Church stand as the most notable structures here.

Charles Le Moyne founded the settlement in 1657 and built the fortified residence of Fort Longueuil between 1685 and 1690 on the riverbanks. The area gained official heritage status in 1993 to preserve its architectural layers from different periods.

The name comes from Charles Le Moyne, the founder who established the first settlement here. The streets today show how the community evolved from a trading post into a residential and commercial hub that residents still actively use.

Rue Saint-Charles serves as the main street where you will find restaurants, shops, and public offices clustered together. Walking through the older lanes near the river is pleasant and easy to navigate.

The archaeological remains of Fort Longueuil lie hidden beneath Saint-Antoine-de-Padoue Cathedral. This buried history led to the area receiving National Historic Site status in 1923.
