Description
The collegiate church of Santi Pietro e Orso (in French, Collégiale des Saints Pierre et Ours) is a religious building in Aosta, in northern Italy. Together with the Cathedral of Aosta, it constitutes the most important testimony of the history of sacred art in the Aosta Valley. Of particular interest are the ancient Ottonian frescoes preserved between the roof and the cover of the central nave, and the cloister with its medieval capitals.
