 It was the seat of the former Diocese of Lombez, suppressed by the Concordat of 1801 and divided between the Diocese of Bayonne and the Archdiocese of Toulouse.This is a 14th-century brick church with an ornate pink-and-white five-tiered octagonal bell tower constructed c. 1346.A plaque to the right of the plain west entrance records the visit of the Italian poet Petrarch in 1330, arranged by the bishop, Jacques Colonna (1328–41), also of Italian extraction, who made Petrarch an honorary canon in 1335.
