May 14, 2026, View of Plön Castle from Prinzeninsel

Schloss Plön is the last large castle construction in Schleswig-Holstein and the state's first three-winged complex. Situated high above the Plöner See, the castle, built between 1630 and 1636, still shapes the town's silhouette today. Three predecessor structures can be proven on the Schlossberg, the oldest dating back to before 1139. From 1156 to 1390, the medieval castle was owned by the Counts of Schauenburg. After numerous changes of ownership, the castle finally came into the possession of Johann II of Schleswig-Holstein-Sonderburg-Glücksburg. His son Joachim Ernst had it demolished and built the castle, which is still largely preserved in its external structure today, between 1630 and 1636. Herrenhaeuser.sh

From 1840, Plön Castle was the official summer residence of the Danish King Christian VIII. For this purpose, the castle was renovated and the furnishings were partly renewed in the style of classicism. At this time, it also received the white plaster that is reminiscent of Danish castles such as Gravenstein and Fredensborg.[9]

Most recently owned by the state of Schleswig-Holstein, Plön Castle was sold due to necessary renovations that the state could not finance. Since January 2002, it has belonged to the "Fielmann Akademie Schloss Plön" and, after extensive renovations, serves the optometry and audiology industry as a training and qualification center. After the castle had not been open to the public for many years due to its use as a boarding school, the new owner opened it to visitors to a limited extent.

Plön Castle is one of the largest castles in Schleswig-Holstein and the only one preserved at an elevated location. It is located in the town of Plön in the district of the same name. The former residence of the Dukes of Schleswig-Holstein-Sonderburg-Plön was built in the 17th century during the Thirty Years' War. It has had a turbulent history, serving, among other things, as a cadet school and boarding school. Most recently owned by the state of Schleswig-Holstein, Plön Castle was sold due to the state's inability to finance necessary renovations. Since January 2002, it has belonged to the "Fielmann Academy Plön Castle" and, following extensive renovations, serves the optics and hearing aid industry as a training and qualification center.

200 lakes close together, with Schleswig-Holstein's largest lake at its center: that's Holstein Switzerland. It's not without reason that this "lake paradise" is one of the most popular vacation regions for water sports enthusiasts, nature lovers, families, and those looking to slow down from the stresses of big city life. The Great Plön Lake, with its deep blue waters and pristine shoreline, entices visitors to spend relaxing holidays on, in, and around the lake. Whether paddling, sailing, fishing, swimming, diving, or golfing near the lake – the options are endless. Furthermore, the 30 square kilometer expanse of water with a depth of 58 meters invites you to enjoy relaxing lake views. And all around the lake, picturesque towns like Plön, Bosau, and Dersau boast a wealth of culture, history, and nature. It's no wonder this lake has been awarded the seal of "Schleswig-Holstein's Favorite Lake" several times in a row.

During this time, the interior was changed significantly. From 1946 to 2001, the castle served as a boarding school before it was sold in 2002 to the owner of Fielmann AG, Prof. Dr. Günther Fielmann, who set up an optician academy there. https://www.herrenhaeuser.sh › ... Plön Castle
