Nativity Co-Cathedral

The Nativity Co-Cathedral was the early nucleus of Cornwall's Francophone community and has been a dominant feature of Cornwall's skyline for over a century. The beautiful structure was designed and supervised by the second pastor of the parish, the Father Paul-Antoine DeSaunhac, a native of Toulouse, France. The first mass was celebrated here on Christmas Day 1891.
