The Vigneux-on-Seine, small town harbour and agricultural until the 18th century, radically changes face and of identity to develop an industrial activity with the arrival at the 19th century of the railroad and the exploitation of the basements.

Thus, on the banks of the Seine, proliferate of the sand pits, disfiguring the landscape and disturbing the natural environment.

The railway line, created in 1870, although disenclosing the city, becomes a real territorial and social fracture. The commune from now on is cut from the Seine and its accesses, formerly required landscapes become by places true dumps. Crossed in slices by the networks viaires and railway of the Sixties, this city illustrates well the complexity of the “suburbia”, with the periphery of the cities.

The asked question through this study is the following one:
How to federate a plan for the future common and shared, through the SCOT and RAINED, who allows this territory to leave his enclavement, while opening again towards the Seine, and to find his geographical and social unit in the memory of the places?

Such is the asked question through this study that required a geographical diagnosis, urban, architectural and landscape particularly thorough with a strong dialogue of all the actors.
