The Stickhausen Castle The Stickhausen Castle has guarded the southeastern entrance to East Frisia since the mid-15th century. For more than two centuries, it was a military fortress, protecting East Frisia from enemy incursions from the east and south. Until 1885, it was the seat of the administration of the Stickhausen district. Since 2019, it has belonged to the Samtgemeinde Jümme.

In 1570, the Freesenhuus (the transept) of today's Haneburg was built. At the end of the 16th century, the castle was rebuilt by Count Drosten Joest Hane. It was expanded to include the southern wing, which, like the castle at Gödens, was built in the Renaissance style. In 1671, the northern wing was expanded and used as a residential castle. After 1933, the building served as a National Socialist farmers' school. At the end of the 1970s, the district took over the castle and restored it to a gem of old architecture through a complete renovation. Today, the castle is the seat of the adult education center.
