The upper level with the sport fields gains its architectural power due to the monumental external staircase. Its generous dimension echoes the size of the upper level offering an unlimited view. In this upper area are situated the soccer and rugby field, as well as tennis and multipurpose fields. These different fields are connected through small paths and the flooring alternates planted and porous concrete areas. An opening in the north allows an impressive belvedere on the canal Ourcq.
