Santa Marta Castle

Highlight • Castle

Imposing castle a few steps from the town of Pancorbo. Even if it was in an open field, it is worth seeing, but climbing the stairs to the tower, admiring the town below and feeling yourself under the cliffs of the upper mountains... an experience to be repeated.

After some minute you will find the best view on the bay of San Sebastián. At the spot there is a small park with some benches as well as a small cafe that offers refreshments. Nearby you can visit the famous statue of Christ which is 12 meter high.

Besides the view point the Mount Urgull offers many small footpaths in the shadow of it's forest. A good opportunity to relax after some intense sightseeing.

The Castle dates from the year 1163 and is located next to the Church of the Assumption. It was first used as a lighthouse in 1853. You can visit it inside (morning: 11 a.m. to 1:30 p.m. and afternoon: 6 p.m. to 8 p.m.). Outside it is full of seagulls and from there you can see impressive views, you can even see the Basque Country from afar. A must if you visit this small city in Cantabria!

Gravel climbing to the castle is not feasible. There are too many stones, and even less so in fog.
