The auditorium is a small independent building, situated on a terrace on the eighth floor of Harrison and Abramowitz's building. It is a diamond-shaped volume. It is not part of the skyscraper's architecture, yet it is incorporated in it through the Pontian pattern of its facing. Seen from above from the upper floors or the sky, the volume, blending in with the pattern of the terrace floor large colored triangles, blue-white, blue-gray, black tended to disappear. Today, as a result of the alterations carried out to the exterior, this effect too has disappeared. Thaks for support: I Volantini
