About 1300, a knight named Conrad von Tronecken is mentioned in document for the first time, and then somewhat later the Feste Troneck (fortification), which, however, is probably much older. Having been destroyed several times, by Cologne, Imperial and French troops, and then finally by an earthquake, only remnants of Dhronecken castle are left now, although a corner tower can still be climbed.
On the old castle's foundations in modern times, commercial buildings were built, and also a bigger, tall building – called the Schloss – which is today used as a forester's office. Also, a barn with beam construction serves as a community centre for the municipality of Dhronecken. The attractively laid-out castle gardens have been continuously planted and tended since 1985.
Below the castle is found a nature play area on both sides of a brook. A ford with stepping stones, a forumlike playing and gathering place on a slope, made out of mighty stone blocks, wooden footbridges over wetlands left in their natural state, playing houses, a suspension bridge and a monorail are the great attractions not only for children, but also for adults.
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.
