The Convent of Müstair, which stands in a vale in the Grisons, is a good exemplar of Christian monastic restoration during the Carolingian period. It has Switzerland's greatest series of symbolic murals, painted c. A.D. 800, alongside with Romanesque frescoes and stuccoes. The most imperative construction of the monastic multifaceted, including two cloisters, is the church devoted to St John the Baptist. Fashioned by a simple rectangular hall some 20 m long, it is closed at the east by three tall semi-circular apses, festooned on the exterior by canopy arcades. The other rooms in the abbey, which for the most part date back to the 18th century, are situated around the chief cloister and contain documents, models associated to the sacred complex, reliquaries, robes, and object of holy art, dating from the 13th to the 18th centuries.
