Eutin Castle was originally a four-winged palace originating from a medieval castle and was expanded over several centuries into a residence. The castle originally belonged to the Lübeck prince-bishops, later it became the summer residence of the Dukes of Oldenburg. The castle was regularly occupied until the 20th century and most of the interior has survived to the present-day. Today the castle houses a museum and is open to the public in summer. It is now owned by a family foundation headed by Anton-Günther, Duke of Oldenburg. The former Baroque garden was converted during the 18th and 19th century to a landscaped park; this is the venue for the Eutin festivals.
A small, late Baroque hunting lodge on the Ukleisee belongs to Eutin Castle. The lodge was built in 1776 at some distance from the main castle at the behest of Frederick Augustus I of Saxony in order to provide a single-storey pavilion for hunting parties and guests attending special occasions.
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.
