The Château de Hohbarr (Haut-Barr) is a medieval castle, first built in 1100, above the city of Saverne in what is now the French département of Bas-Rhin. It was built on sandstone rock 460m above the valley of Zorn and the plain of Alsace. Because of this, it has been called the eye of Alsace.
The current castle was built in 1583 by Jean de Manderscheid. The Peace of Westphalia mandated the destruction of several castles, including Hohbarr, but after the beginning of the War of the Spanish Succession, in 1701, the fortress was back in use. It was abandoned around 1770, but the vault continued to be occupied until the French Revolution.
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.
