The history of Montbonnot-Saint-Martin

Montbonnot-Saint-Martin is a former village of the Grésivaudan, long given over to farming, established on the terraces overlooking the Isère valley.

The municipality changed scale from the 1970s onwards with the creation of the ZIRST science park, since renamed Inovallée, which turned the area into a hub of research and technology companies backed by Grenoble.

It now has close to 5 700 inhabitants and combines a sought-after residential setting, between vineyards, hillsides and views of the mountain ranges, with immediate proximity to the jobs of the Grenoble conurbation.
