Since its creation, the Château du Barroux has been a seigneurial seat, passing through noble families until the 18th century. Originally part of the Principality of Orange and then the Toulouse domain, it became a fief in 1274 under the Comtat.
The castle, initially a fortified keep, was transformed in 1536 by the Rovigliasc family into a Renaissance residence with decorative windows. During the Wars of Religion, it was captured and retaken in 1563 but sustained little damage. Expanded in the 1680s with Vauban-inspired fortifications, it included artillery and defensive features, maintaining its military readiness.
In 1791, it was damaged by revolutionary forces and fell to ruin, serving as a quarry until 1929 when André Vayson de Pradenne began restoration. WWII saw it occupied by German forces, and it was burned down in 1944. Restoration efforts resumed in the 1960s, and the site, now open to the public, is preserved by the Vayson de Pradenne family and the 'Friends of Château du Barroux' association. Recognized as a historical monument in 1963, the castle hosts cultural events today.
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.
