Gaztelugatxe is an island off the coast of Bermeo in the Basque Country that can now be reached by a man-made bridge with 231 stairs. At the top of the island sits the Hermitage of Gaztelugatxeko Doniene. According to legend, visitors should ring the bell three times at the hermitage to make a wish after the climb. Parts of the island were featured in the popular TV series Game of Thrones, though its appearance was altered through visual effects.
