All that remains of the former castle complex today are the ramparts and the gatehouse.
Neuhaus Castle was first mentioned in 1369 and was part of a pledge agreement between Duke Erich IV of Saxe-Lauenburg and the Duchy of Brunswick-Lüneburg. After the Lüneburg War of Succession, it finally remained in the possession of Saxe-Lauenburg and served as an official residence. In the 15th/16th century, it was often mortgaged and at times served as a widow's seat and secondary residence. Under Duke Franz II, it was converted into a castle with fortifications around 1600. It was captured several times during the Thirty Years' War and subsequently lost its importance. From 1719, most of the buildings were demolished and the material used to build the Göhrde hunting lodge.
