Abbey of Trésor Notre-Dame

Abbey of Trésor Notre-Dame is a former Cistercian monastery in Vexin-sur-Epte with surviving buildings including the church, abbess residence, and nun quarters built from regional stone during the thirteen hundreds. The structures reflect the architectural style characteristic of that period.

Founded in 1223 by Raoul du Bus, the monastery received support from Blanche of Castille and Saint Louis during medieval times. It declined significantly after the French Revolution disrupted its religious operations.

The abbey was led by abbesses from noble families who shaped the community's spiritual life over centuries through Cistercian practices and traditions. This female community held significant influence in the region's religious life.

The grounds offer seasonal guest rooms and the former farm building can be rented for private events. Visitors should check availability and access conditions before planning their visit.

The site features a medieval water system with a rectangular stone basin that supplied water to a mill, and traces of the mill machinery still remain visible today. This engineering system demonstrates the monks' practical knowledge.
