Location and description
Beauvoir-de-Marc is located in the northern part of the Isère department on the Bourgoin-Jallieu axis - Vienne, at an equal distance of 20 km between each of these two Dauphiné urban areas.

Saint-Jean-de-Bournay is the closest city at 10 km away, in the shadow of the Lyonnais metropolis approximately 50 km away.

In the 21st century, urbanization brought on by demographic pressure and the suburbanization of Lyon spread diffusely throughout the valley, leading to urban sprawl. At the outset, the frame was constructed with local material: beaten or rammed earth.

Geology
Located in the western region of the Terres froides, covered by glacial formations, the subsoil of Beauvoir-de-Marc is primarily composed of emergent molasses growing on slope sides. The land, covered in hummocks and punctuated by Gervonde valley, contains a small brook running through its foothills.

Various distinguishing features of the moraine glaciers are apparent. The humid prairies contain typical species of these parts: salamanders and crawfish. Certain spots are a reflection of their name; for instance, " the Serfs". This feature posed many technical problems during the 1990/1992 construction of the high-speed line which cut through the village.

The vines that covered our hills have disappeared bit by bit. Land destined for polyculture, the pastures remain. Beauvoir-de-Marc is a land of soft, rolling hills accompanied by wooded countryside, unaffected by deforestation, unlike the steep slopes of the Combes.
