About Aosta Cathedral#

Aosta Cathedral is the Roman Catholic cathedral in the city of Aosta in northwestern Italy and serves as the seat of the Diocese of Aosta. The building has medieval origins and has been the principal church of the city for many centuries.

The cathedral complex includes a main nave, a medieval bell tower and a crypt that contains older burial material and religious fittings. Visitors typically view the exterior architecture, interior liturgical space and the crypt areas that illustrate the building’s long religious use.

The church was established in the early medieval period and has been altered and maintained over subsequent centuries to serve as the bishop’s church of Aosta. It has functioned continuously as the city’s principal ecclesiastical building.

The cathedral stands in the historic centre of Aosta in the Aosta Valley of northwestern Italy, within the city’s compact old town.
