The Évêques-de-Trois-Rivières Mausoleum is a funerary monument in Trois-Rivières, Quebec. It was built in 1965 and 1996, as part of a renovation campaign at Assumption Cathedral aimed at replacing the crypt with a community room in the basement. It is located in the Saint-Michel cemetery, which was opened in the early 1920s. This modern monument, which includes a mausoleum with ten tombs and a funeral chapel, was built according to the designs of architects Jean-Claude Leclerc and Roger Villemure.
