The complex includes church and monastery and its origins date back to the eleventh century when it was in the hands of the Vallumbrosan monks. The current buildings are from the twelfth century. The church went also through many modifications over the years, but it maintains in broad terms the shapes of the Romanesque period, presumably the work of Lombard builders. It has facade and external sides made of blocks of sandstone and Lombard band frieze. The portal shows, in the lintel and in the lunette, bas-reliefs with archaic subject and style.
The bell gable, built in the Sixteenth/Seventeenth century, is over the apse zone. From the same period there are two chapels obtained by transforming the original transept. The interior, with a single rectangular nave covered by wooden trusses, preserves important frescos from 1260-80.
The monastery, already abandoned during the Sixteenth century, was partially demolished in the Nineteenth century as a consequence of damage caused by an earthquake.
