Count Johann Friedrich von Ostein developed Niederwald as a hunting area from 1764; thirty years later he had artificial objects of antiquity such as the ruin built. The artful constructs served as entertainment and landscape design in the sense of late Baroque garden culture. The Rossel castle ruin stands on a nearly perpendicularly falling rocky promontory. From there, a spectacular view on Binger Loch, the Mouse Tower and the Ehrenfels Ruin opens up. The fanciful creation consists of a lightly elevated round tower and a rectangular building. The Niederwald landscape park of today can be reached from two sides, from Assmannshausen and Rüdesheim, by chair lift or cable car. In addition, the Rheinsteig trail runs directly past the ruin.
