Not much to add to Fred's comment. Except that behind the church and just to the left of the cemetery entrance, there is a tiny chapel (where Zoe de Bonchamps, famous for saving the lives of 5,000 Republican soldiers imprisoned by the Chouans in the abbey church, is buried) with a commemorative plaque in honor of Casson's fighters, donated by the Vendée Military Association.

The Church of Saint-Louis was built in 1841. It contains a listed alabaster bas-relief dating from the 15th century depicting "the adoration of the Magi between two saints." The bell tower is listed as a natural heritage site because it is home to greater mouse-eared bats, a very rare breed of bat. You'll find a water tap at the entrance to the cemetery near the chapel, behind the church, and a few benches if, like me, you're not only short of water, but also of energy.

A more direct alternative in terms of time and kilometers than the EV1 to reach Sucé from the Canal. Still, more gravel/mountain bike than touring with panniers in my opinion.

Beautiful medieval castle. The main building is more recent. As a side note, the Isac River fed the castle's imposing moats, now dry, before being channeled to the current marina.
