Pierre Mauroy Stadium
The interval between the envelope and the stands houses all the circulations as well as the numerous exits required for safety reasons. This gallery, an open-air space of welcome and transition, accessible at ground-floor level from the forecourt, constitutes a foyer on the same scale as the stadium and gives people outside the enclosure a glimpse of the playing field.
A moving roof consisting of two sliding rigid panels enables conversion of the stadium from an open-air venue to an immense covered hall. A new arena located under the turf is revealed as an extension of the stands by moving half the playing field sideways. This arrangement greatly increases the variety of sports and shows that this new facility can accommodate.
