Four enormous fans are a key feature of the plaza. The center of the square has a pleasant, shaded micro-climate. The soft lines of the fans are in marked contrast to the surrounding skyscrapers' jagged and crystalline character. The fans conceal the broad stairways down to the square's more informal and intimate rooms, below ground level. There is a celebratory atmosphere in the square, thanks to the large, domed steel structures, the materiality of the fans, and the fertile vegetation. The square forms the hub of the international financial center and in every respect reflects the area's high architectural quality.
