Willis Tower, the building formerly known as Sears Tower, Mid-Century Modernism. West Loop, Chicago.
110 stories tall, its black aluminum and bronze-tinted glass exterior has become emblematic of Chicago. Its innovative structural design laid the foundation for the supertall buildings being built today.
Architect Bruce Graham and structural engineer Fazlur Khan utilized the bundled tube system for the building to resist heavy wind loads. This structural system would prove highly influential in skyscraper construction. It has been used in most supertall buildings since then, including the world's tallest building, the Burj Khalifa.
Across from Willis is 311 South Wacker Drive with its distinctive crown inspired by the top of the Tribune Tower.
