Brief synthesisThe city of Paris is built along a bend in the River Seine, between the confluence of the Marne and the Oise Rivers. The conserved buildings of the Universal Exhibitions that took place in Paris in the 19th and 20th centuries are numerous on the banks of the River Seine. The city of Paris owns the public areas, the Hôtel de Ville, the parish churches and numerous other plots of land and buildings. The “Cahier des prescriptions urbaines et paysagères pour la mise en valeur des Berges de la Seine dans Paris” (Urban and Landscape Requirements for the Enhancement of the Banks of the Seine in Paris), prepared in 1999 by the city, the State and the autonomous Port, is the reference document for all activity and installations on the banks. The “Specifications de prescription des installations saisonnières” (Seasonal Installation Requirements), approved in 2015, aims to control the temporary use and occupation of the thoroughfares of the lower quays of the banks of the Seine in Paris.
