The parish church of Saints-Pierre-et-Paul is a former abbey church built between the 9th and 19th centuries.
Once past the classical and baroque portal, you enter the Gothic bays of the nave. The last double bay of the nave is Romanesque, as are the transept, the choir and the flat chevet chapels. These parts date from the late 12th and early 13th centuries. They are representative of a transitional style towards the Gothic period. The great originality of this building lies in the fact that its chevet is extended by two superb superimposed chapels dating from the 11th century. The crypt and upper chapel each have 3 naves of four bays ending in 3 semi-circular apsidioles. The chapel of Saint-Sébastien (the upper chapel) features superb late 15th-century tapestries depicting the life of Saint Aldelphe, whose tomb was once kept in the Carolingian confessional of the building, as well as superb cubic capitals finely chiselled in relief.
The 12th-century Chapter House houses a seasonal tourist information centre.
