Incourt is the commune of Jodoigne with the most traces of ancient history. It encompasses the villages of Glimes, Incourt, Opprebais, Sart-Risbart, Piétrebais, Chapelle-Saint-Laurent and Roux-Miroir, and is watered by the Great Gette, the Thorembais, the Orbais, the Brombais and the Piétrebais streams. Incourt has many vestiges of the past : the burial mound of Glimes dating from the Gallo-Roman period, the medieval castle farm of Opprebais, the “Gustot” windmill in Opprebais, the Chise farms at Piétrebais, the Opprebais quarry – testament to the industrial past of the commune.
