Church built in the 12th century in a region traveled by pilgrims to Compostela. The town of Conzac was ruined during the Hundred Years War, in the 15th century. The church may have been ruined at this time. It was restored in the 17th century but the town did not recover. The building has a cross plan, with a single nave, and ends in a semicircular apse. The nave was rebuilt in the 17th century. It is covered by a wooden ceiling. The square of the transept had a cupola on pendentives. The sculpture of the capitals is important: riders, characters, animals, ornaments. The apse is decorated with two floors of arcades. All the capitals are sculpted (griffins, birds, interlacing). The apse is covered in the bottom of the oven. The north transept, covered in panelling, retains its vaulted apsidiole. The southern brace was destroyed. The bell tower, which rises above the transept, has been truncated and only retains one floor with four arches on pilasters on each side. A spiral staircase rises between the north apsidiole and the apse.
