Legend has it that it was young girls who were turned to stone for dancing on the moor instead of going to vespers. This legend was created in the 17th century by the church to combat the many paganisms prevalent in Haute Bretagne at that time.

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.

A private property, a beautiful half-castle, half-manor. It is sometimes possible to visit the garden. If it is not opened, the gate will be closed and there will be a sign in front of the entrance.
