Residence of the Dukes of Plön

The first duke of this line was Joachim Ernest of Schleswig-Holstein-Plön, the second youngest son of Duke John. On the occasion of his marriage to the Gottorf princess, Dorothea Augusta, the new ruler decided to build a palace fit for himself and his family. The project was financed ''inter alia'' by the respectable

After Duke Joachim Ernest, the castle went to his son, ''Hans Adolf'', who, however, as a general in the service of the Emperor, rarely stayed in Plön and the duchy was largely represented by his wife and mother. Joachim Frederick, who followed ''Hans Adolf'', also resided here. After he died in debt in 1722 without male heirs, the castle stood empty for seven years and some of the furniture was passed to his creditors. The castle experienced its cultural heyday from 1729 onwards under the last duke, Frederick Charles. He introduced a baroque court and had the interior of the castle decorated in the

Boarding school

In 1946, with the permission of the British military government, the Plön Castle State Boarding School (''Staatliche Internat Schloss Plön'') for boys and girls was established in the castle. The boarding school utilised the entire castle grounds. The castle itself was used to accommodate the boys and the Princes' House the girls. The boat house and other outbuildings were purchased by the school. Lessons took place in the nearby Plön Castle Grammar School (''Internatsgymnasium Schloss Plön'' now the ''Gymnasium Schloss Plön'') in ''Prinzenstraße''. Its use as accommodation left its mark on the old castle, which became increasingly dilapidated. Advice in 1986/1988 showed that the site needed major investment and would only be saved from ruin by spending tens of millions of

Sale and reconstruction

After several unsustainable bids to the future of the castle, Günther Fielmann submitted an offer in 2002. Because this offer included an elaborate argument of the various benefits to the public, Schleswig-Holstein's state parliament approved it in 2002 Consequently, the ''Fielmann Akademie'' foundation purchased the castle for 3.6 million Euro. Günther Fielmann summarised the state of the monument at that time: :: ''When we took over the castle in 2002 it was in a deplorable condition. The broad baroque era hallways had been converted to rooms for school children, using light-weight walls. Barely anything of the original floor plan was visible and the structure had been badly damaged everywhere you looked.'' Over four years the castle has been reconstructed in accordance with preservation and heritage orders. The total costs amounted to more than 35 million Euros

supported the project with 11.8 million Euros. The reconstruction was completed in 2006.
