Vienne Cathedral is a medieval Roman Catholic church in the city of Vienne, France. Dedicated to Saint Maurice, it was the episcopal see of the primate of the ancient Septem Provinciae and of the Archdiocese of Vienne until its abolition confirmed by the Concordat of 1801. It today serves as co-cathedral of the Diocese of Grenoble-Vienne. The present-day building, erected from 1130 onwards, was classified a French national heritage site in the list of historic monuments of 1840.
