Just before entering the Palatinate town of Neustadt an der Weinstraße lies the ruins of Wolfsburg Castle, a medieval hilltop castle built by Count Palatine Ludwig the Kelheim to protect the route from Neustadt to Kaiserslautern, probably at the beginning of the 13th century. The castle was used as a residence by Albrecht von Lichtenstein, who was not allowed to leave it without the permission of the Elector. After the Wolfsburg was rebuilt due to destruction during the Peasants’ War in 1525, imperial troops burned it down completely in 1633. Since then, only the ruins remain, which entered the history books in 1848 as the meeting place of the March Revolution.
