Open House Chicago

The Chicago Architecture Foundation’s Open House Chicago is a free public festival that offers behind-the-scenes access to more than 200 buildings across Chicago.

The Chicago Architecture Foundation’s Open House Chicago (OHC) is the city’s annual architecture festival. For one weekend in October you can explore Chicago’s most iconic and unique architectural treasures. From mansions to sacred spaces, theaters to private clubs, hotels to secret rooms—OHC gives visitors a behind-the-scenes look at many of the city’s great spaces that are rarely, if ever, open to the public.

Here’s your chance to venture into new neighborhoods, learn the stories of Chicago’s buildings and experience the diversity and culture of each community.

OHC is completely free-of-charge—no registration or tickets are needed. So gather your friends, plan your itinerary and mark your calendar for October 14-15, 2017!

What's new in 2017?

Logan Square and Avondale will be making their Open House Chicago debut this year, while Pilsen and Ravenswood will be back. Areas from last year will be back too, such as the Armour Institute building on IIT's campus and Temple Sholom in Lakeview, as well as many downtown areas.
