Aosta - Collegiata di Sant'Orso

The collegiate church, dedicated to Saint Ursus of Aosta, existed here already in Carolingian times. Ursus, who may have been Irish, was a missionary, who supported the Bishop of Aosta. When an Arian became bishop of Aosta, Ursus and other canons left the cathedral and settled outside the walls of Aosta at the present site of the collegiate church of Saint Ursus.

A Romanesque church was built around 1000, but this church got rebuilt, altered and enlarged many times over the centuries. Most seen here is probably from the 15th century. There is a choir screen with three arches, behind the arches are the canons´ stalls.
