Mata Bejid Castle is a rectangular fortress built originally during Muslim era. It has two towers on both sides, quite deteriorated, the one on the North consists of an interior room covered with a pointed vault (keep), and the one on the South has a low solid body and the upper one habitable. The castle is divided into two large areas, the main square (it was converted in recent times into a farmhouse, of which the arches of the zahúrdas that overlooked this large courtyard are preserved) and the Islamic fortress (a higher niver with respect to to the rest of the castle).
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.
