We are here in Nogent, in the Haute Marne, on the Sud Champagne technology cluster. This cluster is the site of innovation in the field of materials, but it is also a successful example of a cluster in a rural environment. First of all, it is a beautiful story, because this location owes nothing to chance. The department has a history of metallurgy and had its industrial heyday in the 18th and 19th centuries, with forges, foundries and cutlery. At the beginning of the 20th century, bold men and women gambled on the territory's main asset: know-how.A daring gamble that has paid off, because by encouraging industrialists to pool their experience, Nogentech has laid the foundations of a European cluster that is a melting pot between companies, research with the UTT and the CRIT Mdts, university training with the UTT and the technology cluster's business incubator. Today, this virtuous ecosystem has become an international reference in the field of metals, particularly in the medical device, automotive and aeronautical sectors.
