Château du Bouilh was built in 1786 for Jean-Frédéric de la Tour du Pin-Gouvernet by architect Victor Louis. The neoclassical semicircular château was built to host King Louis XVI on his visits to the area. There are 30 bedrooms, numerous grand salons, a library, vaulted ceilings and vineyard, a neo-gothic chapel, water tower, and seven hectares of caves.
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.
