Plön Castle

Plön Castle is a Renaissance fortress built on elevated ground overlooking the town, combining symmetrical stonework with ornamental details typical of its period. Inside, multiple chambers and corridors connect different wings, with windows positioned to offer views across the surrounding landscape.

Construction began in 1632 under Duke Joachim Ernest and was finished rapidly despite the turmoil of the Thirty Years War raging elsewhere. This speed of completion reveals the region's relative stability and the duke's determination to establish a grand seat of power.

The chapel inside reflects Renaissance craftsmanship and remains a focal point where visitors can see the care taken with decorative details of that era. It shows how learning and artistic expression were valued within aristocratic life.

The exterior remains visible year-round and can be approached from pathways around the hill, though interior access is usually restricted. Comfortable walking shoes are recommended since reaching the building involves walking uphill and navigating stepped paths.

Since 2002, the castle has housed a specialized training center for optometry studies, transforming this historic structure into a working educational facility. This modern use has kept the building active and provided an unexpected second life for the centuries-old fortress.
