Château de Pibrac was built in 1540 to the site of older castle. It was damaged during the Revolution in 1794 and restored in 1887. The renaissance style residence is built of red brick. The castle itself consists of an old body and wings. The north wing is flanked by a round tower with terrace and has a staircase. The castle park, open to the public, was designed by the landscape architect Eugène Bühler in 1897.
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.
