A record-setting engineering feat and still looking fresh nearly 65 years later, 71 E. Wacker is a quiet star on Chicago's riverfront. Look at that slick stainless steel and glass with the alternating horizontal bands–would you have ever guessed it was completed in 1959? Designed by architect Milton Schwartz and engineer Henry Miller, the Executive House was the tallest reinforced concrete building in the US when it was built, and the first high-rise hotel built in Chicago since the Great Depression.
