Valsery Abbey is a former Premonstratensian abbey located in Cœuvres-et-Valsery, Aisne, France. It was founded in 1124 near the Forest of Retz, which the Premonstratensian canons doubtless helped to clear.
Whatever buildings remained of the abbey after the Revolution, when all monastic houses in France were suppressed, were ruined during World War I and abandoned. The site was declared a historic monument site in 1986, since when much investigation and restoration has taken place.
The only walls still standing belong to the dormitories of the canons and the chapter house, which is the focus of the site with its polychrome decoration and floor tiling. The rest of the site is buried under 2 meters of earth.
