Between Provence and Dauphiné, dominating the cluse where the Durance flows, the Citadelle of Sisteron dominates the sky, crowning the town with its walls, bastions and keep. The view from here is breathtaking, stretching for 150 km and offering one of the finest vantage points in Haute Provence. It bears witness to eight centuries of architecture and history. The keep and sentry walk, built on the narrow rocky spine, date back to the 12th century. The tiered bastioned enclosures dating from the 16th century of the Vauban project, designed in 1692, only the powder magazine was built.
Major alterations were carried out on the north face in the mid-19th century. It was at this time that the magnificent underground staircase linking the fortress to the town was carved out of the rock.
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.
