The church of San Claudio al Chienti is a Romanesque building that is located in the town of Corridonia (Macerata), in a remote location, in the valley of the Chienti river.
Documented since the eleventh century, it is one of the most important and oldest examples of Romanesque architecture in the Marches, still intact in its original conformation.
The church has numerous typological peculiarities, such as the shape of a Greek cross, semicircular apses along the perimeter and two cylindrical torrri. The building also is on two floors with a lower and an upper church.
The stairs to the balcony and the entrance portal of the upper church, in Istrian stone, was added in the thirteenth century.
