The castle is gigantic and beautiful to look at, unfortunately it has been surrounded by a construction fence for ages. Unfortunately, you can't see much. Whether the detour is worth it, everyone has to decide for themselves.

Definitely a highlight, but unfortunately, the castle was covered in scaffolding when I visited. The castle dates back to the Middle Ages but was later almost completely rebuilt.

This medieval castle is one of the most beautiful in Biscay. It is located in a beautiful setting, on a hill and on top of some rocks, and is surrounded by a century-old forest.
