The stadium has also a peculiarity: half of the "Grand Stade" field is situated on hydraulics lift and massive tracks that raise and slide it above the other half of the field in three hours. This creates a second lower level floor plan and surrounding seats called "Boîte à Spectacles", where basketball, tennis or music shows can take place. The "Boîte à Spectacles" can be configured to have a variable capacity, from 6,900 to 30,000 seats. In November 2014, it hosted the 2014 Davis Cup finals between France and Switzerland, where an attendance record was broken for the highest-ever officially sanctioned competition tennis match. In 2017 it hosted the Davis Cup final again.
