Ourscamp originated in the 7th century as a priory, named after St. Eligius, bishop of Noyon. St. Bernard of Clairvaux himself founded an important Cistercian abbey there in 1129, beautifully situated in a park. The impressive ruin with weathered arches of the Gothic choir is the remains of an enormous former church, built in the transition from Romanesque to Gothic. However, the `Salle des morts’ from the 13th century has been well preserved and is used as a church. Together with the hospital, it is the only building in this Cistercian style in France, as can be seen from the three rows of windows above each other. Other parts were rebuilt after 1949. (open Tue-Sun 9-12 and 14-18 hrs).

Ourscamp Abbey is located a few kilometers from Noyon, in the upper Oise Valley. Founded in 1129, it is the second-oldest Cistercian abbey in Picardy. It has been destroyed and rebuilt several times. Its longevity and conflicts have contributed to the abbey's transformations: from religious building to hospital and manufactory; over the centuries, it has served various purposes. Admire the ruins of the abbey church's Gothic choir, a magnificent stone structure. The nave, of which nothing remains, had nine sides, now symbolized by pine trees. Finally, the 13th-century sickbay, also known as the mortuary, is also worth a visit. Anecdotally: the abbey's name dates back to the 7th century. In 641, King Dagobert's advisor began construction, and according to the story, he used a bear to transport the heaviest materials...
