Dave Castle, also known as Fernan-Núñez Castle is a château in the village of Dave, Wallonia. The château stands on the banks of the Meuse. It was originally a medieval structure, the centre of power of the influential sieurs de Dave, but was ruined in the 17th century, and re-constructed in the 18th and 19th centuries by the Dukes of Fernan-Nuñez, whence the alternative name
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.
