St Jean’s Church was built at the end of the thirteenth century (1272-1282), later than the bastide which encircles it.
Originally the church had a magnificent, 35m long and 12m wide nave, which ended in a flat apse to the east. The façade was framed by two square towers.

The four, exceptionally large bays of the nave were covered with rib vaulting and
reinforced with buttresses.

The vaults collapsed in 1771 to be replaced several times with panelling until in 1982 an exposed timber roof frame was erected.
