The church is built on an elongated plan with three cross-vaulted bays.
The chancel, dating from the 12th century, has a flat chevet flanked by a sacristy to the north. The nave, rebuilt in the early 19th century, has six round arched windows, and the sanctuary has two windows. The bell tower, also rebuilt in the early 19th century, is covered in clay, whereas flat tiles were used for the nave and choir.
It should be noted that the bell tower suffered a fire at the end of the 19th century, and certain elements of its reconstruction are still visible.
