Strictly speaking, the “Old Castle” in Rodalben is not a real castle. Rather, the rock massif made of red sandstone is a prehistoric refuge, which was naturally protected by rocks and a rampart.

According to legend, an old woman lived here. Later, a shepherd and a damsel of the castle met there. When their love was forbidden, both drowned in the Moosalb. Two swans still swim at Klug'sche Mühle today, reminding them of the two young people. The cave is interesting and easy to get to.

If you follow one of the staircases that lead here and there up the rising flanks of the gorge, with a bit of luck you will discover the cave-like hermitage in which a hermit is said to have once lived. Inside there is a simple stone cross on a cracked base. The text on it is repeated on the cast-iron plaque next to it. If you take the trouble to decipher the couplets, you will learn more about the details. According to them, the cross is reminiscent of a tragic love death that is connected to Wilenstein Castle: "At Aschbach and immediately in the grave, the knight's bride is killed by a shepherd boy." The corresponding legend of the unfortunate "Fräulein von Wilenstein" and her beautiful shepherd boy can be found in Friedrich Wilhelm Hebel's collection of Palatinate legends. So the "hermitage" ultimately turns out to be part of an overall design concept that wanted to make the walk through nature a romantic and intellectual experience. A bit of horror story included.
