Cité Descartes: The History and Identity of a Unique Technology Park
The Birth of the Cluster
Founded in 1983 by the French government and local authorities in Île-de-France, Cité Descartes was established with the construction of the ESIEE. Bull and the University of Marne-la-Vallée subsequently set up operations there, and since then, the site has grown to include numerous stakeholders in the sustainable city initiative.
