Les Halles

Paris 1st

Lying within a 4,3 hectares area, the project proposed by SEURA architectes in association with the landscape designer Philippe Raguin, creates a clearly delineated and comprehensible single space that fully expresses the size of the site and recreates generous views over Paris.
The project places emphasis on a planted environment by introducing a large meadow between two wooded borders. Atolls positioned over this planted carpet create a slight sense of movement and provide a setting for mature trees.
A central lane crosses the site, reaching from the Bourse de Commerce building to Boulevard de Sébastopol, and passing below the roof of the Canopée cutting across the promenade reaching from Rue Montorgueil to Rue du Pont-Neuf. Two lanes complete the grid running next to the wooded borders to the north and south and alongside Rue Rambuteau and Rue Berger.
Adjacent to the southern transept of the Saint-Eustache church, the stepped Place René-Cassin retains the “listening head”, the emblematic statue sculpted by Henri de Miller. As it nears the Canopée, the park becomes an esplanade that combines water features, planted islands and a bandstand.
Park keepers’ huts, metalwork and fibrous concrete benches all form part of the street furniture specially designed for this park.
