The ducal Widow's Palace in Plön was the widow's seat of the Duchess Dorothea Christina (Dorothea Christine). During its history the building has also served as an orphanage and was modified several times. Today it houses Plön's district museum.
The Widow's Palace was originally a stately home dating to the Middle Ages, which was mentioned for the first time around 1385, and was a fief of nearby Plön Castle. The original building was renovated around 1540 and was used for various purposes, during the rule of the dukes of Plön, including acting as an orphanage from 1685. From 1756 it was extended to become the widow's seat for Dorothea Christina, the mother of Duke Frederick Charles. In the 19th century the court apothecary was moved to the palace. Since the 20th century the building has housed the district museum for the district of Plön.
The barrel-vaulted basement of the palace dates to 1540, after when the building was converted and extended several times. Other alterations to the structure were made in 1639 and 1685, but it was given its present baroque style largely around 1756, although the front was redesigned around 1842 in the classicist style. The palace is a two-storey building under a high mansard roof. It has nine wings and a plastered façade facing the town; its other elevations are in brick. The interior character is that of the 19th century transformation; on the upper floor, the rococo ballroom of 1756, which faces the garden, has been preserved.
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.
