First mentioned in 1240. The castle complex has been gradually renovated for several years. It's always worth a visit and the view is great.

It can only be viewed from the outside as it is privately owned; still quite attractive.

You can visit the ruins, some of which are currently being restored, and you can even go up to the tower for a donation.

Here was the donkey castle that gave the valley its name. Unfortunately, only a few remains of the wall are left. But the view from up here is fantastic!
