Château de Langoiran was built in the 13th century by the Escoussans family, one of the most famous families of Gascony. The donjon (fortified central tower) is one of the largest in France. It overlooks the Garonne Valley and offers a good view for visitors.
The castle of Langoiran was owned successively by the families of Escoussans, Albret (from 1345 to 1378), and Montferrand (from 1378 to 1590). Bertrand III de Montferrand was Soudan de la Trau. He married Isabelle de Preissac, daughter of Arnaud de Preissac, Soudan de La Trau, (member of the Order of the Garter) and Marguerite of Stratton (daughter of John of Stratton).
After being ruined by multiple unsuccessful wars, the owners were forced to sell their land and the castle to a gentry family from Bordeaux: the Arnoulds. The castle of Langoiran and its seignory were mentioned as early as the 11th century. The older parts of the remaining castle date from the 13th century and the Renaissance.
The seignory of Langoiran was one of the most famous and powerful of the Duchy of Aquitaine. For centuries, it had been involved in quarrels between the kings of France and England, both hoping to obtain its accession. When the Duchy of Aquitaine belonged to the English kings and not to the Kingdom, the successors of Henry II Plantagenet were called 'Kings of England and Aquitaine'.
The Lords of Langoiran always supported the King-Duke, other than Bérard d'Albret, who had to fight at the end of his life on behalf of the King of France.
References: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.
