The Catacombs of Paris is a course of more than two kilometers course filled with underground galleries of old quarries. Since April 2017, the new exit, designed by the architect Yoonseux, offers to the visitor a sensorial experience after a long journey through the penumbra and a climb of more than twenty meters by a spiral staircase. The glazed awning diffuses an opalescent light marking the return to the "day" to the visitor. The walls of the Catacombs of Paris exit are coved in white high-performance surface Corian®. The exit is designed to be an "in-between" before the visitor rejoins René-Coty Avenue.
The architect's choice of Corian® was made because he was looking for a white mono-material which was sufficiently rigid not to require frameworks at the level of openings, and flexible enough to accept carved incisions that give movement and lightness to the whole. The choice of a 24 mm thickness, twice the original thickness of the plate, makes it possible to obtain sufficient rigidity without a visible frame. The vision of the interior and exterior is thus identical.
The staging of the project marks a landmark in the urban profile of Avenue René-Coty; it is part of the recent renovation of the Catacombs of Paris and contributes to the experience of some 500,000 annual visitors for whom after a circuit of 2 kilometers, 20 meters underground, experience a sensation of suffocation. For this reason, the decision was made to arrange the exit of the Catacombs so that the visitors can regain their spirits in a calm and luminous setting.
The walls in Corian® surface, seamlessly treated, are luminous and are reflected in the glazing. The entry of light into the west-oriented urban slot is the sensorial experience proposed to the visitors. This outdoor relaxation area is designed to offer visitors a stopover.
