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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
