The Château de Vaudémont is a ruined 11th-century castle. At its greatest extent the castle measures about 500 by 250 metres.
The castle is one of a group of four castles built around the same time on highland sites along the Moselle valley between Nancy and Metz in northeast France. The other three castles are Dieulouard, Mousson, and Prény; of the four, Château de Vaudémont is the largest and best preserved. It was built as a hill castle in the 11th century for the Counts of Vaudémont, possibly for Gérard I (1071 – c.1120). The architect is unknown. The remains are part of the curtain wall and the keep, the so-called tour Brunehaut (Brunehaut tower) constructed with recycled Gallo-Roman remains. It was repaired during the 15th century, dismantled in 1639 on the orders of Louis XIII, and restored in 1930.
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.
