The Chicago Architecture Foundation’s Open House Chicago (OHC) is the city’s annual architecture festival. For one weekend in October visitors 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.
