Join a tour which focuses on Modernism, the dominant visual style of the 20th century, which continues to strongly influence design in the 21st century. Modernism has affected the shape of everything from houses to furniture and appliances, cars and even fashion. But the most spectacular effect of Modernism has been the modern skyscraper made of steel or reinforced concrete with vast areas of glass. It is a product of the age of mass production. Chicago is widely considered the birthplace of the skeleton frame, which forms the core of the modern skyscraper. On your tour, learn about how two men made a lasting impact on Chicago, Architect Ludwig Mies van der Rohe and politician, Mayor Richard J. Daley. Enjoy superb views of the riverfront while walking along the River Walk. Highlighted buildings include Marina City, the Daley Center and the IBM Building. Tickets purchased for experiences run by the Chicago Architecture Center help build the greater Chicago community. When you hit the pavement on a walking tour, set sail on an award-winning river cruise (Chicago's First Lady), or visit the Center, you’re helping fund Chicago Architecture Center education initiatives like Girls Build!, Teen Fellows and the Newhouse Architecture + Design Competition. Or you may be helping to keep programs like Open House Chicago free for participants for years to come.
