Gaztelugatxe is an islet on the coast of Biscay. On top of the island stands a hermitage, dedicated to John the Baptist, that dates from the 10th century, although discoveries indicate that the date might be the 9th century.
In the year 1053 it was donated, by don Íñigo López, Lord of Biscay, to the monastery of San Juan de la Peña near Jaca in Huesca. Medieval burials from the 9th and 12th centuries have been found on the esplanade and in the hermitage.
In 1593 it was attacked and sacked by Francis Drake. Among other incidents, it has caught fire several times. On November 10, 1978, it was destroyed in one such fire. Two years later, on June 24, 1980, it was re-inaugurated. The hermitage belongs to the parish of San Pelayo in Bakio.
The hermitage also houses votive offerings from sailors who survived shipwrecks.
The hermitage is accessed by a narrow path, crossing the solid stone bridge. According to legend, after the slightly strenuous climb to the top of the crag one should ring the bell three times and make a wish.
HBO filmed scenes for season 7 of its fantasy series Game of Thrones at the islet. Gaztelugatxe stood in for Dragonstone, with a digitally created castle on top of the islet.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
