Goldbeck Castle, Medieval castle in Goldbeck, Germany.

Goldbeck Castle is a former moated castle at the southern edge of Goldbeck, a village in the Wittstock/Dosse municipality. Its moat, once fed by the Dosse River, is dry today. The complex was rebuilt repeatedly over the centuries and adapted to the taste of each period. Beside the main gate is a narrow single-person slip gate, the only one still existing in Brandenburg.

The castle was first documented in 1325 and served the Counts of Ruppin as a fortress until 1524, when it passed to Elector Joachim I. This transfer occurred after the Ruppin family line ended.

The village of Goldbeck was first mentioned in a document in 1247, when it belonged to the Lords of Werle. The castle later served as a residence for the robber knights Hans von Bosel and Klaus von Königsmark in 1424. From the mid-1980s, visual artists converted the castle into studio apartments for the Association of Visual Artists of the GDR.

The castle is located near Wittstock/Dosse and can be reached by local roads. The visit requires no special preparation, and the site is accessible on foot.

The castle houses Brandenburg's only remaining single-person passage gate, a narrow portal installed beside the main entrance. This rare architectural feature shows the security requirements of defense design.
