Luna castle dates from the 13th century and was built under control of 'Guzmán the Good' upon a fortified convent of ribat or Muslim origin, in the 11th century. It is rectangular with five crenelated towers, and its interior is structured around a central courtyard.
Property of the Dukes of Arcos, the Ponce de León used the castle as a residence and there is evidence that the Catholic Monarchs visited the city and stayed there.
The Luna Castle is a symbol in itself for citizens of Rota, Cadiz, and proof of this is its presence on the coat of arms of the village. It has housed a hospital and a school, and is currently the location of the City Hall of Rota.
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.
