The system enabling the removal of a tensioned marquee comprises a central circular fixed rail (1) and a second concentric fixed peripheral rail (2). The second rail has a greater radius than the other rail. The marquee cloth roof (3) is tensioned between the two rails. The roof is held by wheeled carriages inserted in the rails. The carriages are held apart by a rigid edges (5) fixed to the roof. The tensioning system enables the removal of very large tensioned marquee roofs.
