The construction of Château de Conches-en-Ouche started in 1034 by Roger I of Tosny. The castle was captured by Philip II of France in 1199 and again by the English during the Hundred Years' War in 1364. It was recaptured by Bertrand du Guesclin in 1371. The castle was lost again in 1420, retaken in 1440, lost once more in 1441 before being finally taken by the French in 1449. In 1591, members of the Catholic League took refuge there; a potential base for enemies of the monarchy, it was demolished afterwards. The castle was classified as a monument historique in 1886.
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.
