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.

Translated from English-Butrón is a castle in Gatika in the province of Biscay in northern Spain. It originally dates back to the Middle Ages, but its current appearance owes its current appearance to an almost complete reconstruction begun in 1878 by Francisco de Cubas. The castle looks like a fairytale, inspired by Bavarian castle models. Wikipedia (English)

Unfortunately also a place with too many holiday apartments. But the view over the coast is beautiful. Gaztelugatxe is still visible in the background.

This hermitage from the mid-19th century is a reconstruction of an older one that already existed in the place. On its lintel door you can see the wooden inscription: "Maddalen 1846", the year it was built. It has a small roof with a table and benches where you can take shelter if the rain surprises you.
