... 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.

From the road bridge you can enjoy the view of the course of the Aff, its weir and its footbridge. The bucolic setting invites you to stroll.
