San Clemente al Volmano, also known as the Abbey of San Clemente, is a Romanesque-style, former-Benedictine church and monastery found in a rural site, on a hill above the Volmano River, in the frazione of Guardia Vomano of the town of Notaresco, in provincia di Teramo, Abruzzo, Italy.

According to the Chronicon Casauriense (1182) is that while emperor Ludovico II himself commissioned the Casauria abbey after his release from the imprisonment by Adelchis of Benevento.

Other sources claim it was founded instead by Louis II's daughter, Ermengard of Italy.

The layout of the church has three naves each ending with a semi-circular apse and supported by brick or stone pillars or columns.

In the nave on the right, a polychrome wooden bust represents Pope Saint Clement, whereas on the other side there are interesting remains of frescos.
