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.

Spanning over 3,300 hectares, the Ermenonville forest, along with those of Halatte and Chantilly, forms the vast Trois Forêts massif. Once owned by the monks of Chaalis and other nearby abbeys, it is now renowned for its moors, Scots pines, and sandy soil, home to rare wildlife such as the European nightjar and the praying mantis.

Very nice road/path in the woods, quiet. Be careful, some segments south of the D126 are not tarmac, and less suitable for racing bikes.
