Zenith, a Music Palace able to contain 10.000 people. The central core of this theater- building is made of an ellipsoidal concrete body. On this strong perimeter are placed the covering beams made of steelworks.
Around the cylindrical shape body a structure constituted of 22 small girders which bear a kind of parvis.

This roofing, partly anchored to the concrete walls and partly leaned on the floor, has been conceived to act as the supporting skeleton of the outer cladding: an orange membrane.

Fabric used is silicone coated fiberglass due to its strength but above all to its translucency.

As a matter of fact the fabric behaviour with light was a fundamental requisite for designers: at night the Zenith lights up from inside and becomes a beacon visible from a great distance.
