Origin and history

The Priory of Saint-Pierre-en-Chastres is a former monastery located in the forest of Compiègne, on the eponymous mountain, in the commune of Vieux-Moulin (Oise, Hauts-de-France). Founded in the 9th century by Benedictines of the Abbey of Saint-Crépin-le-Grand de Soissons after a gift from King Charles le Chauve, it initially welcomed a religious community before being entrusted to the celestines in 1309 under the impulse of Philip IV le Bel. The site, marked by a flamboyant Gothic chapel added in the 14th century to Louis d'Orléans' initiative, declined after the French Revolution, when the last monks left it in 1791 and the buildings were sold as national goods.

The current remains, classified as historical monuments in 1905, include a partially preserved nave, a columned gate, bas-relief sculptures and a chapel with windows characteristic of primitive Gothic. The site, now owned by the community of communes of Compiègne (ARC), illustrates the architectural and spiritual evolution of monastic orders in Picardia, from Carolingian origins to revolutionary dissolution.

The isolated location in the forest, near the ancient Roman road from Compiègne to Soissons, suggests a role both spiritual and strategic. The Benedictines, then the celestines, maintained a monastic life rhythmic by the prayer and reception of pilgrims, before the political upheavals of the eighteenth century brought to an end almost 900 years of religious history on this site.
