Eltz Castle (Burg Eltz) is surrounded on three sides by the Elzbach River, a tributary on the north side of the Moselle. It is situated on a 70m rock spur, on an important Roman trade route between rich farmlands and their markets. It is still owned by a branch of the same family that lived there in the 12th century, 33 generations ago. The Rübenach and Rodendorf families' homes in the castle are open to the public, while the Kempenich branch of the family uses the other third of the castle. The Palace of Bürresheim (Schloss Bürresheim), the Castle of Eltz and the Castle of Lissingen are the only castles on the left bank of the Rhine in Rhineland-Palatinate which have never been destroyed.
The main part of the castle consists of the family portions. At up to eight stories, these eight towers reach heights of between 30 and 40 meters. They are fortified with strong exterior walls; to the yard they present a partial framework. About 100 members of the owners' families lived in the over 100 rooms of the castle. Platteltz, a Romanesque keep, is the oldest part of the castle. In 1472 the Rübenach house, built in the Late Gothic style, was completed. Remarkable are the Rübenach Lower Hall, a living room, and the Rübenach bedchamber with its opulently decorated walls. Between 1490 and 1540, the Rodendorf house was constructed, also in Late Gothic style. It contains the vaulted 'banner-room'.
The Kempenich houses were finished about 1530. Every room of this part of the castle could be heated; in contrast, other castles might only have one or two heated rooms. From 1965 to 1992, an engraving of Eltz Castle was used on the German 500 Deutsche Mark note.
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.
