In June of 2009, Périphériques Architectes of Paris, France participated in the second edition of the Contemporary Art Exposition Saint-Germain-des-Près with an installation on Place Furstemberg. The Pink Ghost installation was a sculptural transformation of the center of the square with a preservation stance. Made of pink epoxy, the installation enveloped four trees and a streetlight to a height of 2.5 meters, and covered the entire surface of the small central square.

While the covering work was in progress, the architects cleverly added approximately twenty chairs and five coffee tables under the resin, to turn this exterior urban space into an ‘interior’ lounge/salon situated outside. The project was meant to raise questions about the status of public space in the city. After its removal from the square, Pink Ghost was rebuilt in the French pavilion at the Biennale of Architecture in Venice, as a memory of the plaza and its new use.
