Bellefontaine Abbey, Trappist monastery in Bégrolles-en-Mauges, France.

Bellefontaine Abbey is a Trappist monastic community in rural land south of Angers with stone buildings in Neo-Gothic style. The central church and surrounding residential wings form an enclosed compound dedicated to monastic life.

Founded around 1120, when a charter was recorded between Pétronille de Chemillé, first abbess of Fontevraud, and Pierre, first abbot of Bellefontaine. In 1305 Bertrand de Got learned here of his election as Pope Clement V and gave a stone Virgin still kept in the church. After the Revolution the ruins were bought in 1816 by Urbain Guillet, who re-established a Trappist community; the church was rebuilt and inaugurated in 1879.

The abbey's name comes from a spring, "beautiful fountain", on the site. From 1966 the community ran the Éditions Monastiques Abbaye de Bellefontaine, publishing texts on Eastern and Western spirituality. Guests staying in the hôtellerie join the offices, with lauds at 7 a.m. and vespers at 6 p.m.

The site is reachable from Cholet, the nearest larger town with train connections. Visitors who wish to stay overnight should arrange in advance by phone, as the monastery accepts guests for extended stays.

In 1305 Bertrand de Got, then Archbishop of Bordeaux, stopped at the abbey and there learned of his election as Pope Clement V. He gave the community a stone statue of the Virgin, still set against the right pillar of the choir. The abbey also kept a publishing house from 1966, issuing texts on Eastern and Western spirituality.
