The Château Saint-Sixte is a 12th-century castle in the commune of Freistroff. It stands on a small plain between Freistroff and Rémelfang. It was built in the 12th century by the seigneur Wirich de Valcourt.
During the Renaissance, it was transformed into a residence and was altered again in the 18th century. It was saved from ruin by the Gehl family in 1986. Separated from the village on the left bank of the Nied, it has a strange oval plan, surrounding by ancient moats. The six originally separate buildings are roofed with two slopes of tiles and arranged around an entirely enclosed courtyard. In each corner, a polygonal staircase tower gives access to the upper storeys.
On weekends and public holidays, the owners offer guided tours.
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.
