Events

Its foundations are entrenched in the foundation of Longueuil itself. The third church in this location since 1697, it has dominated the city skyline since 1887 with its neo-Byzantine-style dome. The Saint-Antoine-de-Padoue co-cathedral promises a visit that is both enlightening and fascinating, with its chapel dedicated to Marie-Rose, its museum, its crypt, and its countless anecdotes deeply rooted in the most ancient history of the South Shore.

A stop not to be missed.
