Culture
The Saint-Pierre-en-Chastres Priory was founded in 1309 by Philippe IV le Bel and incorporated into the newly established Order of the Celestines. Its ruins in Vieux-Moulin have been protected as a monument historique since 7 June 1905. Saint-Pierre-en-Chastres is considered a rare example of late 14th-century architecture in the region.
The Church of Saint-Mellon was rebuilt in 1860 according to plans by Grisart, the architect of the Palais de Compiègne, at the request of Emperor Napoleon III and Empress Eugénie. The bell tower, designed as a vestibule, has two strongly projecting roofs that give it a pagoda-like appearance. The church also contains a carved wooden Stations of the Cross by P.A. Brément, who was the parish priest of Vieux-Moulin from 1860 to 1896.
On the northern slope of Mont Saint-Mard stands the Pierre qui tourne megalithic monument, also known as Pierre Torniche. A burial chamber was discovered beneath the Pierre qui tourne dolmen during the Second Empire. The Vivier Frère Robert comprised a fishpond and a mill that were transferred by the Augustinians of Royallieu in 1620.

Nature
The Ru de Berne flows through Vieux-Moulin and powered the former watermill after which the village was named. At 137 m, Mont Saint-Pierre-en-Chastres is one of the highest points in the Forest of Compiègne. Grimp à l'Arb offers 13 courses in the Forest of Compiègne, attached to centuries-old trees.
The Promenade des Gorges du Han leads to the Étangs de Saint-Pierre, which are designated as an attraction along the route. The six Warin ponds became the present-day Étangs de Saint-Pierre. The Grotte des ramoneurs is also located along the promenade. It has been closed to the public since 2000 and serves as a refuge for biodiversity; at the same time, it is home to at least 130 horseshoe bats.
