Plön Castle, built 1633–1636 as a residence for Duke Joachim Ernst, is the largest castle in Schleswig-Holstein and an important Renaissance building. It served as a ducal seat, Danish summer residence, Prussian cadet institute and boarding school before being extensively renovated. Today, the highly visible, white castle is home to the Fielmann Academy. Here are the most important epochs of the castle's history: Origin: The castle stands on the foundations of an older castle from the 12th century. Construction period (1633–1636): Duke Joachim Ernst of Schleswig-Holstein-Sonderburg-Plön had the three-winged brick castle built as his residence during the Thirty Years' War. Duchy and Danish period: Until 1761 it was the seat of the Plön Dukes. After the line died out, it fell to the Danish royal family, served as a widow's residence and later as a summer residence for King Christian VIII. During this time (from around 1840) the building was given its present white appearance. Prussian Era & 20th Century: After 1867, the castle became a Prussian cadet institute. In the 20th century, it housed a National Socialist elite school (Napola) and later a boarding school. Fielmann Academy: In 2002, Prof. Dr. Günther Fielmann acquired the castle and established a non-profit optician academy there.

Transport: Until the 1970s, milk was not transported in 40-ton tankers, but elaborately in cans. Collection process: The dairy farmers placed the full cans on the side of the road or at the milk collection point. The milk truck, often a smaller truck or even a horse-drawn carriage in earlier times, picked them up. Dairy trips: The cans were taken to the dairy, emptied, cleaned and often returned the next day. The transport was labor-intensive, as each can had to be lifted individually.
