Le Grau-du-Roi combines the characteristics of a small town with a fishing port, a significant seaside resort with 120,000 resident visitors during the summer period, and the largest marina in Europe (Port Camargue, with 4,800 berths). Due to significant urban pressure and environmental challenges (OGS, Natura 2000, flood risk, coastal law, etc.), the municipality currently has very few available spaces for further development. Located in the heart of Le Grau-du-Roi's urban fabric, the Mediterranean Eco-district project covers 106 hectares, encompassing the last remaining non-urbanized spaces in the municipality, as well as the historic urban center and key mobility and public service facilities.

With a keen focus on promoting sustainable urban development for the city, the municipality, in partnership with the regional public land authority, is promoting this coherent and ambitious project that addresses urban diversity, attractiveness, and mobility challenges. One of the key ambitions of the overall urban project is to enable Le Grau-du-Roi to play a new role in the coastal system: both urban and natural. Its history, current urban functions, and especially its position in the territory's infrastructure will allow Le Grau-du-Roi to become a major "urban centrality" within the ensemble formed by La Grande-Motte, Aigues-Mortes, and Port-Camargue.
