The Château de Mirabeau is a medieval castle overlooking the village of Mirabeau. Its origins date back to the 12th century, when it was first mentioned as a fortified structure. Initially owned by the Abbey of Saint-André, the castle underwent various changes over the centuries. The castle played a crucial role in the local economy, especially during the late Middle Ages, by controlling a key river crossing.
The current structure, likely built in the late 16th to early 17th century, features a quadrilateral layout with four circular towers. It has been remodeled and expanded, particularly in the 18th century, and includes a chapel and various living quarters.
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.
