The abbey is in Cagli along the road between Acqualagna and Piobbico, near the Candigliano river, in a hamlet called Abbadia di Naro, surrounded by hills and dominated by the homonymous castle.
Founded by Benedictine monks in the 13th century and in the past a flourishing monastery, only the central part of the restored church is left, within which many traces of frescoes on the walls, among which a fragment dating back to the 14th century represents the “Madonna enthroned with Child”. The façade is hut- shaped with a central portal and window. In the back you can see a sail-shaped belltower and a single Romanesque lancet window in the back wall. On the right hand side a portico with three low quandrangular pillars.
The different construction phases date back to early Middle Ages and Medieval times. Embedded in the walls you can still see the old columns of the nave, some of which are in terracotta, others in earthernware tiles and they all have stone capitals, whereas, opposite the façade, there are still remains of the portico of the back side of the church.
Due to some renovation works, the inner church is with single nave and exposed trusses and the main altar replaces the original one which leant against the wall. People got to the presbytery, which was formerly higher than the modern one,using a staircase underneath which a crypt has been found. The presence of aisles explains why there are higher older windows.
