The essential

— Saint-Jean Baptiste church

This church was rebuilt in 1754 by Viscount Des Androuins, lord of the place, and placed under the patronage of Saint John the Baptist. The external appearance of the church is interesting due to the variety of materials used – red bricks and white stone are superimposed in several equal layers. The facade is covered with flat tiles.
