Osterstein Castle Gera
The Osterstein castle, situated on the hill Hainberg, was erected on the site of a former castle complex of the early Middle Ages. Throughout the Middle Ages it was the residence of the feudal lords of Gera. The palace was destroyed in the Second World War, and unfortunately not rebuilt. The donjon from the 12th century and some buildings of the lower palace court are still preserved. The donjon is used for art exhibitions, such as painting, graphics and photography.
