Built in the 16th century and remodeled several times, this church has the shape of a Latin cross without aisles. The south transept is the most recent. It features stained glass windows signed by the master glassmaker F. Razin in 1945. The main altarpiece depicts the martyrdom of Saint Lawrence on an iron grill, heated by burning coals. The cemetery, partly encircling the monument, was moved in 1943.

... and we almost drove past. The medieval town is worth visiting twice! The buildings have great architecture and there are plenty of restaurants.
