St. Mary's Catholic Church Doors Open Carleton Place

St. Mary's Catholic Church

St. Mary’s first mass was held on Christmas Day 1884. Visitors can tour the original church and the new wing. Look for the plaque commemorating the work of first pastor in the old church. And, in the new wing, see the baptismal font carved from a large boulder that was brought here from Napanee (the church was built around it).
