The Altschlossfelsen - Rochers du Vieux Château - Old Castle Rocks - is a rock outcrop formed of bunter sandstone in the Palatine Forest of Germany, near the border with France.
The 1,500-metre-long rock wall is located on a hill known as the Brechenberg near Eppenbrunn, 406 m above sea level.
The Altschlossfelsen is well known because of its many, diversely shaped rocks, caused by weathering, and its rare lichens. A popular footpath runs along the foot of the rocks that continues to the village of Roppeviller in French Lorraine.
