Walter, a young miller of Bözingen, was in love with a young lady from the village of Flüglistal. The young lady was stunningly beautiful and known to all as “little dove”. At that time, the castle of Rondchâtel was the stronghold of the crooked knight Ingelram. On the day of the marriage, he attacked the wedding procession upstream of the gorge. He killed the fiancé and attempted to kidnap the bride. So as not to fall into the hands of the knight, the young lady threw herself into the chasm and disappeared there, gliding like a white dove. A short time later, the castle of Rondchâtel was captured and destroyed, and the knight Ingelram was killed. In spring, lovers are said to hear the plaintive cries of the beautiful young lady in the gorge.
