Hornbach Abbey

Hornbach Abbey is a former Benedictine monastery founded around 741 in the historic town of Gamundias (today Hornbach) by St. Pirminius. Today, only structural remains of the convent buildings exist, supplemented by a monastery museum, as well as a modern chapel with the historic tomb of the monastery's founder.

The site of Gamundias had Celtic and later Roman settlements, each with a mountain sanctuary on the grounds that was later built over by the monastery; predominantly Roman coin finds indicate use from 496 BC.

Hornbach in the Bliesgau belonged to the Diocese of Metz. After the founding of Murbach Abbey in 727, endowed by Count Eberhard (Etichonen), Pirmin came to Gamundias around 740/741. There, Count Warnharius from the Wido family (ancestors of the Salian dynasty) endowed the construction of a Benedictine monastery; Sigibald († 741), Bishop of Metz, signed the foundation charter and confirmed the monastery. As a proprietary monastery of the Salian dynasty, Hornbach Abbey possessed far-reaching privileges. After his death in 753, St. Pirmin was buried in the monastery. With the rise of his cult of veneration, the importance of the place grew, which is also evidenced by several renovations and extensions, as well as numerous documents mentioning tribute payments to the monastery. The saint's tomb was moved to the east apse; from 827, Pirmin – alongside Peter – was named as the patron saint of Hornbach Abbey. Around 850, it was subject to the Zell collegiate church near Worms, in whose vicinity it also owned several proprietary churches and properties. In 1087, Emperor Henry IV gifted Hornbach Abbey to Bishop Rüdiger Huzmann of Speyer. In the 11th century, a monumental pillar basilica, measuring 72 meters in length, was built, featuring five towers and a westwork in addition to the two apses. Emperor Henry V granted the monastery the right to mint coins, which was exercised until about 1230. In the 12th century, the building was renewed. The monastery provided important impulses for development in Upper Lorraine, documented by numerous village and farm foundations by the monks. When it fell under the influence of the Counts of Zweibrücken, its decline began.

In 1548, only three monks lived here, and in 1557, Hornbach Abbey was finally dissolved – in the course of the Reformation. The monastery's assets, current income, and buildings were used for the establishment of a princely state school, which was responsible for training the next generation of pastors and higher officials needed in Palatinate-Zweibrücken, or for preparing them for university studies. In 1631, the school was moved to Zweibrücken. After that, the unused building increasingly fell into disrepair. Wars also led to further destruction; for example, during the Dutch War, French troops razed the crossing tower of the basilica.

The so-called Hornbach Sacramentary, a 10th-century codex, made by the Hornbach scribe-monk Eburnant on behalf of his abbot Adalbert of Hornbach (approx. 970 to 990), is located in the Central Library of Solothurn.
