With its dynamic curves and wide facade facing the cathedral of Chartres, its esplanade and “belvedere roof garden”, the new cultural and sports facility is becoming the distinctive identifying factor of the new station hub district and a community facility. The cauldron-shaped hall and its ambulatory, a circular agora, provide optimum visual comfort and strengthen the feeling of belonging during events. The roof garden with its wide selection of plants provides the city with a spectacle, and its inhabitants with a new public space.
