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
Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
