In the 9th century, Bishop Samuel of Worms (841-856),[1] who was also abbot of Lorsch Abbey, acquired the relics of St. Cyriacus, one of the highly revered Fourteen Holy Helpers, in Rome and placed them in the church in Neuhausen, which soon adopted St. Cyriacus as its patron saint and was linked to a collegiate church.

[2] This castle had a polygonal shield wall and was located slightly west of Neuhausen Abbey on a peninsula between the rivers Pfrimm and Mühlbach.

[4] Eberwin von Kronenberg (d. 22 April 1308), the Bishop of Worms, laid the foundation stone in 1300 and also oversaw the completion of the building after the founders had died.

By the early 16th century, the monastery held possessions in Osthofen, Pfeddersheim, Alsheim, Einselthum, Westhofen, Gundersheim, Blödesheim, Eich, Hochheim, Leiselheim and Pfiffligheim.

In 1327, Count Palatine Adolph of the Rhine died and his widow, Irmengard of Oettingen moved into Liebenau monastery with her children.

The historian Johann Friedrich Schannat provides the inscription on her grave, which no longer exists, on 172 of his Historia episcopatus Wormatiensis.

The Dominican chronicler Johannes Meyer (1422-1482)[12] reports that during one of these visits, Beatrice gave birth to Rupert,[13] who would be raised by Irmengard in Liebenau until age 7.

The Liebenau monastery enjoyed the very special favour and affection of the Palatinate ruling family, because Irmengard and her princely relatives had resided there.

Irmengard of Nassau died at Liebenau in January 1371, in the odor of sanctity as the Historical Society for Hesse puts it.

[20] Johann Friedrich Schannat reports that the inscription on his grave called him a Dominican from Augsburg and reformer of the Monastery.

After the failed attempt to dissolve in 1561,[22] Elector Frederick III sent his officials to the monasteries of Himmelskron and Liebenau in May 1562.

The officials were to explain the elector's gracious intentions to the nuns and to inform them that he, as their sovereign, fervently wished that they would "behave as obedient children and allow themselves to be educated about the pure divine message".

The envoys were received in a room, where all the residents of the monastery had gathered, 13 nuns and 9 lay sisters, all dressed in their religious attire.

The Prioress then frankly declared that her parents had destined her for the monastery at an early age and she had entered the convent and that she would never betray the faith in which she had been raised and that she would not take off her religious attire and that she and her subordinates never left the convent and that her clothes therefore could not give offense and that she held their singing and reading and monastic rules for a laudable, Christian activity and that they could not accept a preacher and that they would not listen if one were provided, because they could not judge the many faiths that were proclaimed at the time.

We could not persuade the prioress and in the end she told us, we should ask the nuns and lay sisters for their opinion and they unanimously declared that they would never forsake their faith and begged the Elector to leave them in peace.Some time later, Frederick III visited the monastery in person.

During the 19th and 20th century, a leather factory named Heyl’sche Lederwerk Liebenau[31] was located on the grounds of the former monastery.

Its owner, Baron Ludwig von Heyl zu Herrnsheim excavated the site in 1929 and extensively documented his finds.
