Limberg Castle was built in the 13th century at a strategic site on the border of the bishoprics of Minden and Osnabrück, probably by the Bishop of Minden. Even before that, a castle or fortress was said to have stood on the site, at which Duke Widukind stayed. Around 1300, the castle became the possession of the counts of Ravensberg as a fief and was extended by them. The castle is first recorded in a document in 1319. On the death of the last Count of Ravensberg, Bernard in 1346, the Limberg, as part of the County of Ravensberg, fell to the later Duke of Jülich and Berg.
In 1554, Limberg Castle was damaged by fire but restored. As a result of the War of the Jülich Succession, the castle was allocated in the 1614 Treaty of Xanten to the Elector of Brandenburg, who - after it had been captured and held during the Thirty Years' War by the Count Palatine of Neuburg, had it manned with a small contingent after 1647. During the war, it had been guarded by a 30-man garrison which was meant to guarantee the integrity of the castle, but when they were detailed to support the siege of Lippstadt, it was not difficult for the Count Palatine to seize it.
In 1662, the castle's garrison of twenty men was transferred to the Sparrenburg, thus ending its history as a military base. Towards the end of the 17th century, the castle gradually deteriorated and was barely usable for military purposes. In 1695, in a rescript by Elector Frederick I of Prussia to the Ravensberg bailiwick, it was recommended that the house of Limberg be demolished since, due to its state of disrepair, it had become uninhabitable. The tower was still used as a gaol until 1805 and was finally sold in 1832. In the 1980s, an association was founded to preserve the castle ruins.
The square twelve-metre-high bergfried (tower house), with sides measuring twelve metres long, was restored in 1989 and may be visited. In addition there are also several defensive banks, the wall remains of the palas and parts of the enceinte as well as the moat. At the castle is a 600-year-old 'court lime' (Gogerichtslinde), which used to act as the site of a regional magistracy or Gogericht.
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.
