Open House Chicago
19-20 October 2019

Open House Chicago, presented by the Chicago Architecture Center (CAC), is the largest free architecture and urban exploration festival in North America. OHC is your chance to get inside 250+ of Chicago's iconic skyscrapers, repurposed mansions, opulent theaters, exclusive private clubs, world-renowned architecture/design offices, cutting-edge industrial facilities and breathtaking sacred spaces. No tickets or reservations are required at most sites.

Chicago is known as the "Second City" but it is arguably the first city for architecture in the United States. The historic home of Daniel Burnham, Louis Sullivan, Frank Lloyd Wright and Mies van der Rohe, Chicago is now the laboratory where most of the world's tallest buildings are designed. In addition to exploring Chicago's Downtown "Loop" district, Open House Chicago gives visitors access to architectural gems in neighborhoods all over the city and close-in suburbs.

The Chicago Architecture Center (, founded in 1966, is the largest organization of its kind in the world with an annual audience of over 1 million locals and tourists. The CAC is dedicated to inspiring people to discover why design matters. In 2018, it opened a new Center with expanded and immersive exhibits, and continues to offer a comprehensive program of tours, lectures, and youth education activities. The CAC launched Open House Chicago in 2011.
