Vornbach Abbey, dedicated to the Virgin Mary and Saint Benedict, was founded in 1094 by Count Ekkebert of Formbach and his wife Mathilde, and also by Count Ulrich of Windberg.
It was dissolved in 1803 during the secularisation of Bavaria. The monastic buildings came into the possession of Franz X. Bachmayr, and in 1857 into that of the Baron von Schätzler. The abbey's Austrian possessions were taken by the state.
References:Ehrenbreitstein Fortress was built as the backbone of the regional fortification system, Festung Koblenz, by Prussia between 1817 and 1832 and guarded the middle Rhine region, an area that had been invaded by French troops repeatedly before. The fortress was never attacked.
Early fortifications at the site can be dated back to about 1000 BC. At about AD 1000 Ehrenbert erected a castle. The Archbishops of Trier expanded it with a supporting castle Burg Helferstein and guarded the Holy Tunic in it from 1657 to 1794. Successive Archbishops used the castle's strategic importance to barter between contending powers; thus in 1672 at the outset of war between France and Germany the Archbishop refused requests both from the envoys of Louis XIV and from Brandenburg's Ambassador, Christoph Caspar von Blumenthal, to permit the passage of troops across the Rhine.
