200 COOL PLACES. 
48 HOURS. GO. 

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 places and 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 17-18, 2015!
