According to the tradition, the foundation date was 1192, and the site of the building, at 620 metres above sea level in the upper valley of the Lierbach near Oppenau, was determined by a donkey which threw off a sack of money at this remote and inaccessible spot. In the same year a wooden chapel was built, which was gradually extended to be a Premonstratensian monastery. In 1196 the foundation charter was issued by Duchess Uta of Schauenburg. In 1200 Philip of Swabia recognised the foundation, and in 1204 Pope Innocent III confirmed it. The first abbot was Gerung.
