Châtelard castle was built probably by Rudolph Grossi, bishop of Aosta in 1243 and archbishop of Tarantasia in 1246. It is first mentioned in a document from 1248, and presents the type of circular tower reminiscent of the fortified constructions of Count Peter II of Savoy, to whom Grossi was a close advisor. All around, medieval dwellings of all shapes and sizes dot the land like small sentries with an ancient charm: the Pascal fortified house, the Aragon fortified Manor house, Maison Gerbollier, just above, the home of the Ecours and again, in the village of Derby, the notarial 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.
