Explore Willis Tower and learn how the architects met the challenges of designing a super-tall building in the 1970s. We’ll also visit 311 S. Wacker Drive across the street and compare its Postmodern design to Willis Tower’s Modernism.
Originally developed and named for Sears Roebuck and Co., the Willis Tower was the world's tallest building for almost 25 years. Learn how the architects met the challenges of designing this super-tall building and hear about efforts being made to retrofit the building to meet today's energy efficiency standards. We'll discuss the 5-story crown atop 311 S. Wacker Drive and how the building plays off the neighboring Willis Tower too. Together, these two buildings illustrate the major design and structural characteristics of twentieth century architecture.
