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.
