Neudahn Castle history
Presumably in 1438, during the War of Metz, the castle was burned down. The castle was also badly damaged during the Peasants' War of 1525. However, after the end of the war, the castle was restored, significantly expanded and modernized. In 1689, the French army destroyed the castle during the Palatinate War of Succession. The owner of the castle is Rhineland-Palatinate General Directorate for Cultural Heritage (in German Generaldirektion Kulturelles Erbe Rheinland-Pfalz).
