Susa Cathedral is a Catholic cathedral in Susa, Piedmont, in northern Italy. It is the seat of the Bishop of Susa and is dedicated to Saint Justus of Novalesa. In origin it was the church of the Benedictine Abbey of St. Justus, established in 1029 by Marchese Olderico Manfredi to house the newly discovered relics of Saint Justus. The cathedral is a Romanesque style building. The façade has terracotta decorations and is joined to a Roman gate of the 4th century, the Porta Savoia, to the south. Halfway along the south side stands the campanile, with six levels of mullioned windows.
