Schadeck Castle is the most recent and smallest, but still most interesting of the four Neckarstein castles. It is perched on the high mountain like a bird's nest, which is why it is, in fact, called the 'Swallow's Nest'. After Ulrich II (1236-1257) inherited the 'front castle' from his father Ulrich I and another son joined the clergy, Bligger V, the third son, was forced to build a new castle. However, there was no more room on the mountain ridge where the other castles stood and thus he had to erect it downstream from the front castle on the slopes of the rocky massif that drop steeply to the Neckar River. This location must have caused enormous difficulties during the construction. To save the level ground for the castle complex and provide it with a frontal ditch as protection against the mountainside, a large chunk of the steep rock face had to be hewn out.
The castle itself stands on a rocky basement and appears to literally grow out of the mountain. Along the top of the high curtain wall, the most likely place to be attacked, runs a covered wall-walk with little towers on both sides. They command a panoramic view of the Neckar River valley and the impressive walled town of Dilsberg. Visitors to the castle today walk along a path from Neckarsteinach, which leads through the former frontal ditch. Earlier access was by way of a steep serpentine path from the Neckar. Today the ruin is the property of the state of Hesse and was recently restored at great cost. It can be viewed at any time free of charge and the curtain wall can be climbed.
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.
