Abstract To form an audience chamber in a roofed stadium, at least one truss suspendable from the stadium roof and a canopy removably connectable to the truss. The canopy comprises a plurality of parallel, contiguous elongated panels of flexible material. A close-off curtain is suspendable from the canopy when only a portion of the stadium is to be used as the audience chamber.
