Val-Saint-Lambert Abbey (French: Abbaye du Val-Saint-Lambert) was a Cistercian abbey in the Prince-Bishopric of Liège. It is situated in the Walloon municipality of Seraing, on the right bank of the Meuse, in Belgium, about 13 km (8.1 mi) south-west of Liège. Founded in 1202, the abbey's monks were expelled during the French Revolution.[1] In the 19th century, the building ruins were converted into the Val Saint Lambert crystal factory. The structure is considered to be an important example of Cistercian architecture.
