The Citadel of Dinant (Citadelle de Dinant) was built in 1815 on a site which was originally fortified in 1051 when the region was ruled by the Prince-Bishopric of Liège. The citadel overlooks the city of Dinant and the strategic Meuse river which runs through the town. It is open to the public.
Together with Huy, Liège and Namur, the Citadel of Dinant forms part of the so-called Meuse Citadels.
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.
