Tholey Abbey, Benedictine abbey in Tholey, Germany.

Tholey Abbey is a Benedictine monastery featuring a church from the 13th century with three naves and a rectangular choir. The grounds contain stone foundations from the Frankish period, showing how the site developed from early medieval beginnings through later reconstructions.

Adalgisel Grimo, a Frankish deacon, bequeathed his Tholey estate with its churches to the Diocese of Verdun on 30 December 634; the deed survives in a 10th-century copy in the Koblenz state archive. Monks from Trier were sent at his request, and the abbey remained tied to Verdun throughout the Middle Ages. In 1794 French Revolutionary troops plundered and burned the monastery, which was dissolved the same year.

The monastery follows Saint Benedict's rule, and visitors can experience the daily rhythm of prayers and communal meals with the monks. The community members work in the gardens and workshops, showing how spirituality and practical labor blend into daily life here.

The abbey church is open to visitors, and the monks run a guesthouse and a bookshop on the grounds. The chapter house was renovated in 2008 and a baroque-style pavilion stands on the abbey grounds. As of 2020 twelve monks from five nations live here, so check opening times before planning a visit.

The bell tower houses seven bronze bells, including two medieval ones cast in 1458 and 1459 by the bell founder Wilhelm Czun. These bells rank among the oldest surviving examples of their kind and show the craftsmanship of that era.
