Château de Gréolières was mentioned first time in 1047 when it belonged to the Viscounts of Nice. Counts of Provence decided at the end of the 12th century to enforce eastern part of Provence against the influence of the Republic of Genoa and local nobility. To control the area of Gréolières, the Count of Provence built the new castle around 1220.
In 1235 Count of Provence gave the castle to Romée de Villeneuve. The castle remained in the hands of his descendants, the lords of Villeneuve-Vence, until the French Revolution. The castle and the village were plundered in 1385 during the clashes between Charles de Duras and Louis II of Anjou.
During the Wars of Religion, in 1574, the castle was attacked by Huguenots and again in 1590 by Duke of Savoy. The castle was restored in the early 17th century, but bombed again during the War of Austrian Succession in 1747 by the Austro-Sardinian troops.
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.
