Built in the 11th century and rebuilt in the 12th century, this building is exceptionally north-south oriented. This church is remarkable for its 35m high rectangular bell tower. It has three naves with a shallow transept. The powerful, shaped columns support the round arches. The central vault, which was also built in the form of a semicircular arch, has collapsed. It was rebuilt in the 12th century with a higher pointed arch. Thus, the window under the bell tower opens into the nave and no longer lights the choir.
