Casteau (Walloon: Castea) originated as a village in the Hainaut province of Wallonia, the French speaking south of Belgium. Casteau has become a district of the municipality of Soignies, centred around Soignies (town), and together with the former villages, now districts: Chaussée-Notre-Dame-Louvignies, Horrues, Naast, Neufvilles, and Thieusies.

The village is located between the towns of Mons and Soignies on the road Mons-Brussels. The river Obrecheuil flows through the village. In the past, there were some watermills along the river.

Casteau was already known in neolithic times. A Roman cemetery from the times of Marcus Aurelius has been discovered.


The valley of the Obrecheuil is in the east of the village. This part of the valley is part of Natura 2000. The heart of the village is in the northwest higher part of the valley. The northwestern part of the village is a plain with dispersed houses and farms with typical hedges. The village is the border between the valley of The Haine (Elevation from 20 to 30m) and the plateau of Hainaut (elevation from 80 to 150 m).

Around the village, there are several woods (comprising oaks, beeches, chestnuts, and poplars), fields (comprising potatoes, sugar beets, corn, and wheat), and prairies (for cows and horses). The ground is made of sands and silts.
