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 kilometres (8.1 mi) southwest of Liege. Founded in 1202, the abbey's monks were expelled during the French Revolution. 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.
