It's hard to see this mill. It's overgrown with vegetation, making it almost invisible. It's a shame it's not more prominently displayed.

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

It's really worth visiting! Beautifully renovated and maintained houses from the 15th and 16th century create an amazing atmosphere of a truly historic village. True wonders of ancient architecture.

Maison Yves Rocher is located in La Gacilly. Yves Rocher himself was from this picturesque village in Morbihan. There is a shop, a cafeteria and a museum. 15 minutes away is the Yves Rocher ecological spa hotel “La Grée des Landes”.
