Castillo de Guardias Viejas is a battery built in 1769, near the rocky surface low rise of the Mediterranean Sea. Owned by the Regional Government of Andalusia, the municipality has carried out renovation work in the building, which houses a permanent exhibition of clothes and weapons of the Napoleonic era.
It was restored in 1980. The castle is one of five forts in the town, next to the Moorish Tower Hill, the Square Tower, Tower of the Netherlands and the Tower of Balerma. It has been a venue for musical events such as the Natural Music Festival and the festival Creamfields Andalucía.
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.
