The Séminaire is the historic heart of Sainte-Thérèse and the reason the town existed long before it became a Montreal commuter suburb. The original stone college dates to 1825, with later wings added through the nineteenth and early twentieth centuries; the assemblage sits on a leafy block of rue Saint-Charles and gives the town centre its old-Quebec character.
The building is no longer a classical college — it now houses the Collège Lionel-Groulx, a public CEGEP — but the chapel, the courtyards, and the riverside grounds are open to walk through. If you are interested in Quebec educational and religious history, ask at the reception about visiting the small museum that displays artefacts from the seminary's long career.
