The Château de Ramstein is built on the same crest as the Château de l'Ortenbourg. Standing at an altitude of 384 m, it is dominated by the Château de l'Ortenbourg from which it is separated by a few hundred metres.
It was built around 1293 as a rear base during the siege of Château de l'Ortenbourg by Otto von Ochenstein, during the conflict between Adolf of Nassau and Albert of Habsburg. Originally built as a simple tower to support a siege engine, it grew at the start of the 14th century into a true castle with the strengthening of the tower and an extra wall. In 1421, it was attacked and pillaged by Strasbourg. It was destroyed in 1633 by the Swedes during the Thirty Years' War. At the start of the 19th century it became the property of baron Mathieu de Fabvier, who also owned Ortenbourg. Today, all that remains are the exterior wall and two turrets, built of granite.
Because of the risk of landslides, the castle has been closed to visitors since 1983. The castle has been listed as monument historique by the French Ministry of Culture since 1924. It is the property of the commune.
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.
