In February 2019, “QARTIER” – the first cultural area dedicated to contemporary art in the metro – has opened in Bourse station. In a place where architecture is intimately connected to art, the spectator is drawn into materials such as natural stone and poly-mirrors. A suspended ceiling, surrounded by a staging structure, is sprinkled with light beams that take the shape of the constellations of the solar system. Display windows, projectors and screens allow an active visualization of the art pieces and complete the staging, where the spectator becomes the main actor. Different cultural operators succeed each other there for a defined period. They invest a place with a program of at least three exhibits per year. These include artistic creations made by young and rising artists to bring a genuine cultural dynamic and constantly question the space.
