Tips from the Community

December 16, 2025, Chemin de halage

A towpath, or "chemin de halage," which runs alongside the river or canal, was an indispensable part of the transportation infrastructure in earlier times. Before ships could be propelled by motors, horses walked along the bank, pulling the vessel against the current. This was called "treideln," and that's how towpaths got their name, which has been passed down to this day. Where these paths, located directly on the riverbank, have been preserved, they are popular with hikers and cyclists.

The Great Stables of the Château de Chantilly, built in the 18th century by Louis-Henri de Bourbon, Prince of Condé, are among the most majestic in the world. A masterpiece of classical architecture by Jean Aubert, they have housed the Living Museum of the Horse, dedicated to equestrian art, since 1982. This site has been owned by the Institut de France since 1886.

The Château de Thiers-sur-Thève, now in ruins, is a former 13th-century fortified castle listed as a Historic Monument in 1862. Built as a hunting lodge for the bishops of Beauvais, it is distinguished by its large state room pierced with large windows, a rare example of medieval residential architecture in the Île-de-France region. Partially dismantled in the 15th century, its circular towers, moats, and Gothic remains can still be admired.

The Bruyères de Frais-Vent, located in the Ermenonville forest in the Montlognon woods, constitute an exceptional natural site. It is the only place in the massif where large blocks of sandstone rest on a vast layer of Fontainebleau sand.

Listed as a Historic Monument since 1862, the church of Montagny-Sainte-Félicité stands apart from the village, on the site of a former priory dependent on the Abbey of Saint-Vincent de Senlis. Rebuilt in the 16th century in a flamboyant Gothic style, it is distinguished by its tall, 30-meter openwork octagonal spire, one of the most elegant in the Oise.
