Porte de la Chapelle is located at the junction between the new Arena facility (2024 Olympic Games - 8000 spectators), the Condorcet Campus construction site (2025 - 3500 students), and the ZAC Gare des Mines-Fillettes (150,000m² mixed use district). The development challenge of the 43,000m² site is to transform an environment dominated by road infrastructure into a quality urban, landscaped calm space which gives priority to soft transportation, planted landscaping. An open area which combines monumental vehicle ramps, immense soaring pillars, elongated shelters under the arcades. A hybrid landscape comes to life, both urban hill and planted landscape, a new landmark at an urban scale.
