Hornbach Abbey (German: Kloster Hornbach) is a former monastery founded around 741 in the historic town of Gamundias (today Hornbach) by Saint Pirmin, which soon became a Benedictine abbey. The most important neighbouring abbeys were Bausendorf, Saint-Avold, Glandern, Villers-Bettnach, Fraulautern, Mettlach, Tholey, and the stift of St. Arnual. The neighboring spiritual centers were Trier and Metz. At present, all that remains of Hornbach Abbey are the structural remains of the convent buildings, which have been supplemented by a monastery museum, and a modern chapel with the historical tomb of the monastery's founder.
