Sprengelburg is a ruined hill castle in the county of Kusel in Rhineland-Palatinate. It lies between the villages of Eßweiler and Oberweiler im Tal on the L 372 state road.
Base on what is left of the castle, the Sprengelburg may have been built in the 13th century. The castle was erected at the narrowest point of the Talbach valley and guarded the road that used to run below it in the valley bottom.
The castle lords were the knights of Mülenstein, vassals of the Rheingrafen family in Grumbach. Whether they had the castle built is unclear. The Mülenstein family is recorded from 1317 to 1451. The Lords of Mülenstein were robber knights and inflicted serious losses on the merchants using the road. Consequently, the castle was destroyed by Strasbourg merchants in retaliation for the raids. The exact date of its destruction is not known.
From 1976 onwards, excavations were carried out on the site by students of the University of Maryland under the direction of Professor Higel. The remains of the outer walls, a rectangle measuring 20 by 15 metres, and a round tower, 8 metres in diameter, were uncovered. In the summer of 1978, the skeleton of a woman was also discovered inside the castle. After the excavations were completed, reconstruction work was carried out, initiated by the Department of Monuments in Speyer. The outer walls and the tower were rebuilt, and a round-arched gate was inserted into the outer wall at the rear of the complex as the entrance. Some of the stones found during the excavation were used for this purpose. The modern ascent to the 8.5-metre-high tower, an iron spiral staircase, was added at that time. This leads to an observation deck, although the view from the deck through the surrounding forest is quite limited.
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.
