Dubbed 'Reinvent Paris', the initiative aims to transform a total of thirty-four sites owned by regional authorities into economic, cultural or social spaces. The three unused metro stations are at the Champs de Mars in the 7th arrondissement, the Croix-Rouge in the 6th and Saint-Martin, between the 3rd and 10th arrondissements.

Architects and developers should submit their proposal outlines by November and a shortlist will be made in 2018. Final selection will happen in November 2018. Head here for more information.
