The Château du Bernstein is a ruined castle in Dambach-la-Ville. It is among the oldest in Alsace. It was first mentioned at the beginning of the 11th century, though the northern surrounding wall can be dated to prehistoric times. The upper castle with keep, manor house and advanced works probably dates from the end of the 12th and early 13th centuries. In the Gothic era, the manor house was separated from the keep by a ditch, transformed later into a cistern. Towards the end of the 15th century, the St. Marguerite tower, so called from the name of the chapel there, was built in the rear courtyard.
Around 1835, Félix Dartein cleared the ground of the lower castle to build a house and some outbuildings which have disappeared.
Originally, the castle belonged to the Counts of Eguisheim Dabo. After the siege of 1227, it became the property of the bishop of Strasbourg and seat of the episcopal bailiffs until 1580.
The Château du Bernstein is state property and has been listed as a monument historique by the French Ministry of Culture since 1931.
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.
