"Beau-voir", the town would be well named: "Beautiful to see". The existence of Beauvoir is drowned in the mists of time, certainly in the first centuries of our era.
The "Boutonnière" of the Pays de Bray is a depression 2 to 15 km wide, bordered on each side by more or less marked escarpments (cuestas). Soil erosion is uneven. Some points of resistance have given rise to witness mounds. (The Monts de Sigy, Beauvoir en Lyons..)
In this depression, slight undulations create a varied landscape, composed of hedgerow meadows, wetlands, cultivated fields and vast forest massifs.
There are clayey soils, suitable for pastures for dairy cattle breeding. On the summits and plateaus, the soil is made up of clay and flint, while the lowest areas are dominated by meadows and forests. The soil is very humid, with a ferruginous subsoil (thermal springs) and iron ore, as well as colored clays (ceramics) and glass industry linked to the forest.
In Beauvoir en Lyons, the mosaicist Milan Uzelac has perpetuated the glassmaking tradition on the orientation table. (Orientation table 6 on the Route des Paysages)
