Co-Cathedral of Saint-Antoine-de-Padoue

The Co-Cathedral of Saint-Antoine-de-Padoue is a house of worship featuring eclectic architectural elements in Le Vieux-Longueuil. Its most striking feature is a Byzantine Revival dome that rises prominently above the building's main structure.

The building was constructed between 1884 and 1887 by architects Maurice Perrault and Albert Ménard. Stones from the earlier Fort Longueuil were incorporated into the structure, linking the site's past military use to its religious purpose.

The co-cathedral displays works by Québec artists Louis Jobin and André Achim throughout its interior spaces. These sculptures and artistic pieces reflect how local creativity and religious expression have been intertwined in the community.

The location is easily accessible on foot given its central position in Le Vieux-Longueuil. Visitors should check opening times beforehand, as access may vary depending on services and events taking place inside.

Archaeological remnants of Fort Longueuil lie beneath the site, a fortified residence built between 1685 and 1690. These buried layers tell the story of an earlier settlement that occupied the location long before the cathedral was constructed.
