Kossenblatt Palace and Park are situated on an island in the Spree River, covering approximately 28 hectares, on the southeastern edge of the Dahme-Heideseen Nature Park. A medieval border castle with ramparts is documented at this location as early as 1208. At the beginning of the 18th century, a three-winged Baroque complex was built here, which was completed by Eleonore von Barfus after the death of its builder, Hans Albrecht von Barfus. From 1736 onwards, King Frederick William I used the palace as a residence on occasion.
The castle has a multifaceted history – from aristocratic residence to military and civilian functions, culminating in extensive preservation and renovation work in the 20th century. Since the 1990s, the castle has been privately owned. Based on historical building research, it has been undergoing gradual restoration and development for cultural use since 2023.
The estate includes a spacious castle park, in the gardens of which a café invites visitors to linger. Regular guided tours of the castle and park offer insights into its history, architecture, and current developments, bringing the grounds to life. Civil wedding ceremonies are also possible at the castle.
