The remains of the château de Bar-sur-Seine are the ruins of a medieval French fortified castle, destroyed in the 16th century. The first building was erected in the 13th century, adapted and altered into the 15th century.
The historic importance of the castle was due to its position on the frontier between Champagne (a vassal county of the King of France) and the Burgundy (a duchy allied with the English) during the Hundred Years War. At the time, the château de Bar-sur-Seine was considered the most important in Burgundy. Its architecture is close in style to that of the Château de Peyrepertuse in Aude.
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.
