Willis Tower
description: The Willis Tower is a 110-story skyscraper that displays a striking black aluminum and bronze-tinted glass facade. This combination creates a reflective matte finish that enhances its visual appeal. The building’s unique bundled tube structure provides structural support, maintaining its iconic shape. The tower’s design emphasizes its height and bold elegance. At different heights, three main rectangular structures flank the building that leads up to the top. A prominent white tower at the pinnacle elevates the building’s landscape.
