In Boulogne-Billancourt, a western suburb of Paris, an island in the Seine is being developed into an “artistic micro-city” designed by Jean Nouvel. The project for Île Seguin will create artists’ studios, commercial gallery and auction spaces, an exhibition hall, and a conference center to transform the island into a modern cultural hub.
