Abbaye de Boquen, Cistercian abbey in Plénée-Jugon, France.

Abbaye de Boquen is a former Cistercian abbey in Plénée-Jugon, Brittany. Its abbey church, built in the last quarter of the 12th century, is about 50 metres long and 7 metres wide, with a flat chevet flanked by rectangular chapels. The west facade has four buttresses, a pointed portal with four archivolts, a tall central window and a small oculus. The nave has four bays and three vessels under a modern timber roof, and the first bay, once reserved for lay brothers, opens not onto the side aisles.

The monastery was founded in 1137 and quickly became a significant landowner with farms, fishponds, and town properties across the region. Over centuries it experienced periods of decline and abandonment as broader changes affected monastic life.

The name comes from a natural spring that once flowed through this land. The church reflects Cistercian values of simplicity, with clean lines and minimal decoration that monks sought in their spiritual spaces.

The site is best explored on foot, as buildings are arranged around a central courtyard area. It helps to check visitor information online beforehand to learn about opening hours and any seasonal closures.

Dom Alexis Presse, who revived monastic life here in 1936, is buried in the first chapel of the south transept of the abbey church. The community he founded left in 1970, and the Sisters of Bethlehem then occupied the site from 1976 to 2011.
