Absolutely charming town, lots of little corners with beautiful things. Definitely recommend stopping and enjoying.

Magical town with a fairytale castle. (however, I recommend you swerve the Logis Hotel-Restaurant du Chateau). Or if you can find no other accommodation, at least avoid eating in the restaurant, which was one of the few outright poor places to eat I've found in France.

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