Clairvaux Abbey was a Cistercian monastery in Ville-sous-la-Ferté, 15 km from Bar-sur-Aube, in the Kingdom of Burgundy. The original building, founded in 1115 by St. Bernard, is now in ruins; the present structure dates from 1708. Clairvaux Abbey was a good example of the general layout of a Cistercian monastery. The Abbey has been listed since 1926 as a historical monument by the French Ministry of Culture.
The grounds are now occupied and used by Clairvaux Prison, a high-security prison.
