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.

Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
