Kohlstein Castle is situated on a rocky hillock in the village of Kohlstein northwest of Tüchersfeld and is the most recently built castle in Franconian Switzerland. It is also one of the smallest and most romantic castles. Today it is in private ownership and may not be visited.
The castle may have been built around 1486 by Conz of Hirschaid. It was probably originally an allodial estate of the Lords of Hirschaid. Later, feudal sovereignty passed to the Bishopric of Bamberg.
In 1525 was destroyed in the Peasants' War. It was immediately rebuilt. In 1607/1608 the Hirschaid family had to sell their barony as they were short of money. On 23 May 1608 Wolf Philipp Groß von Trockau zu Tüchersfeld was enfeoffed with the castle and lordship. During the Thirty Years' War the castle appears to have been destroyed because in 1636 a modest new structure was built. It was comprehensively renovated between 1707 and 1714.
A garden house was probably built at this time, which was converted in 1743 into a castle and village chapel.
The Groß von Trockau family, who called themselves from 1658 zu Kohlstein und Tüchersfeld, had to sell the castle in 1713 to Otto Philipp von Gutenberg. After his death, his niece, Maria Anna Groß von Trockau, inherited the castle and estate.
The current structure, a residential building with attached tower, dates mainly to the 18th century. The tower was renovated in 1890.
In 1961 the Groß von Trockau family sold the castle, but not its associated chapel. The castle has had several owners since then.
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.
