Cistercian monks were expelled from this valley in 1796 and their church pulled down. Thirty years later a crystal works moved into what was left, and made the name of the abbey a byword for cut glass.
At a glance
Val Saint-Lambert lies at Seraing, twelve kilometres west of Liège, in the Meuse valley that became the industrial heart of Wallonia. The Cistercian abbey founded here in 1202 was suppressed in the French Revolution; the buildings were sold as public property, and in the 1820s a glassworks took them over. What survives is a rare thing: a monastic site read through an industrial one, with an eighteenth-century abbey front, the works around it, and the Musée du Val Saint-Lambert inside.

History
Hugues de Pierrepont, prince-bishop of Liège, gave land and woods near the city to the monks of Signy so that they could found a house there. The Cistercian order was expanding fast, and through Signy and Igny the filiation of Val-Saint-Lambert runs directly back to Clairvaux. A group of monks settled in 1202 and the buildings of the first abbey were finished before the end of the thirteenth century.
The place was almost permanently a building site. Fires, plundering and destruction followed one another over the centuries — which is probably why the monks of Val-Saint-Lambert, unlike other communities, left little behind in letters and learning. The last abbey dates from the commendatory abbacy of Gérard-Joseph de Harlez, elected in 1748: work began in 1750 under the master mason Jean-Gille Jacob, and was finished when the French Revolution swept the house away. In 1796 the monks were expelled, the church demolished and the buildings put up for sale as public property.
The second life began in the 1820s, when a crystal works took over the abbey buildings and turned the name into a mark known well beyond Belgium.
What you see
The building in front of you is the abbey of the 1750s, known locally as the château: a long red-brick range with stone window surrounds and quoins, a mansard roof, and a pedimented centre. It reads as a country house because that is what a late Cistercian abbey had become by then.
Around it are the works. The contrast is the point of the place: the monastic plan is still legible under a site that spent two centuries making glass, and the museum sits inside the result.
