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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
