Surrounded by a park with a chateau garden with strange woody plants, the two-story Renaissance building with a pointed gable roof is a typical one-house building - there are no outbuildings here. The first floor houses the town's information and tourist center. On the upper floors you can learn what the interior of the castle looked like during the First Republic.
The castle was built between 1566 and 1573 for Georg von Schleinitz. Later owners were the Lords of Starschedel, Wolfgang of Mansfeld, the Princes of Dietrichstei, the Counts of Harrach, the timber merchant Ernst Grumbt and Erwein Leopold Maria Alexius Nostitz-Rieneck. After the end of the Second World War, Schluckenau Castle was expropriated and nationalized.
In 1986 the castle burned down. For financial reasons, the reconstruction works were stopped after 1990, so the castle remained a ruin without a roof. Between 2005 and 2008, reconstruction was carried out with EU funding. In addition to exhibition and event rooms, the building also houses an information office for tourists. The park adjoining the castle is now partly used for public events. The owner of the chateau is the town of Šluknov.

Wikipedia mentions a forestry museum in the castle. However, this is no longer located here.
