The origin of Château de Duras was the church of Saint-Ayrard (now demolished), which was located 1200m from the castle. The church was given in 977 to the Abbey of La Réole by Gombaud, Bishop of Vasconie and Guillaume, Duke of Gascony. In 1087, Bertrand de Taillecavat gave a quarter of the church of Saint-Ayrard to the abbey of La Réole. In 1127 the priory of Saint-Ayrard's villa is destroyed by the Viscount of Besamont. A house and a chapel was then built on the current site of the castle. A charter of 1233 attributed to the prior of La Réole the rights to the city of Duras, as he owned the priory of Saint-Ayrard. The charter is signed by Geraud de Malemort, Archbishop of Bordeaux, Raymond, Bishop of Agen and Guillaume de Bouville, Lord of Duras.
The first castle of Duras dates from the 12th century and was built on a rocky outcrop overlooking the Dropt valley. The castle belonged to the family of Bouville. The castle was captured in 1254, from the Viscounts of Benauges and Bezaume by King Henry III of England after a revolt of the Gascon lords. He passed the castle to his son, the future Edward I.
In the early 14th century, Gaillard de Goth, brother of the first French pope Clement the 5th, inherited of Duras castle. Papal money must have been useful for the construction of a new fortress to replace the former medieval castle. Then, the lands of Duras became property of Arnaud de Durfort when he contracts a marriage with Marquèse de Goth, the Durfort became then Durfort-Duras and the castle remained property of the same family until 1838.
Today Château de Duras is open to the public. The visitor can browse History and Architecture through the 30 restored rooms
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.
