Abbaye de Royaumont

Royaumont Abbey is a former Cistercian monastery located in the hamlet of Baillon in Asnières-sur-Oise in the Val-d'Oise department, approximately thirty kilometres north of Paris.

It was built between 1228 and 1235 under the patronage of Saint Louis, and was then one of the most important abbeys in France. It remained a Cistercian abbey until the French Revolution, when it was sold as a national asset and became an industrial textile site. It regained its religious vocation in 1864, until the Combes laws in 1905. The abbey was then bought by Jules Goüin, and his grandson Henry, an industrialist and music lover, opened its doors to artists, organised concerts there, and made it a place of musical and cultural creation. He donated it to the Royaumont Foundation, which he created in 1964, the first private cultural foundation, which has managed the premises ever since.

The edifice has been classified as a historical monument since 1927 for its remains, and 1948 for the abbey buildings and the park.
