One of the reasons the religious community established itself in the village of Longues was because of the spring that lets out in the monastery pens at the highest part of the orchard.

The water from the spring reached the abbot’s house via a stone pipe. As time went on the water flow was blocked by roots from nearby trees, and the channelling had to be redone from the upper part of the orchard all the way to the abbot’s house.

The arches of this cellar are supported by a decorated central pillar — a rare remnant from the arrival of the monks at the end of the 12th century.

This room is only open to the public on special occasions, such as the European Heritage days (Journées Européennes du Patrimoine) the 3rd weekend of September.
