A historic track in Paris is reimagined with an open grandstand for crowds both big and small.

Located in a previously industrial part of Paris, the 1975 Pont de Sèvres Towers, designed by Badani and Roux-Dorlut, have been reimagined by French architect Dominique Perrault. Renamed Citylights, the once detached office complex now embraces the city with sustainable prism-shaped buildings that illuminate the rapidly developing district (dubbed Trapèze) with a gentle luminosity.
