Attention all locations managers. Ever walked past a beautiful Chicago building and wondered what’s behind those doors? This weekend, you may finally get your chance to find out. Open House Chicago returns Saturday, October 17, and Sunday, October 18, inviting residents and visitors to explore more than 200 architectural, historic and cultural sites across more than 30 Chicago neighborhoods. Best of all, admission is free.
Presented by the Chicago Architecture Center, the 16th annual event offers rare behind-the-scenes access to some of the city’s most fascinating spaces, including historic theaters, skyscrapers, museums, creative studios and neighborhood landmarks that are not ordinarily open to the public.
And with more than 200 destinations to choose from, even lifelong Chicagoans are likely to discover something new about their city.
Behind doors rarely opened to the public
One of this year’s most anticipated attractions is the historic Uptown Theatre, which opened in 1925 and closed in 1981. The landmark theater is welcoming large-scale public access for the first time in decades, offering visitors a rare opportunity to see inside one of Chicago’s legendary entertainment venues.
Other notable destinations include the Cadillac Palace Theatre, the Chicago Board of Trade Building, and the Muddy Waters MOJO Museum, the former Kenwood home of the blues legend that is being transformed into a museum celebrating his life and music.
Visitors can also explore the Stony Island Arts Bank, the Griffin Museum of Science and Industry, and the TimeLine Theatre, along with dozens of lesser-known architectural treasures scattered throughout the city.
The Chicago Board of Trade Building offers a particularly unusual experience. In addition to its magnificent Art Deco lobby, visitors can explore a historic underground vault that once housed valuables and financial records.
Discover Chicago one neighborhood at a time
Open House Chicago isn’t limited to famous buildings downtown. The event encourages visitors to venture into neighborhoods they might not ordinarily explore, discovering the history, architecture and people who give each community its identity.
This year’s lineup includes approximately 20 new sites, with destinations ranging from restored historic properties and neighborhood cultural centers to working creative spaces and urban gardens.
The festival also offers themed itineraries, including theater destinations, skyline views and routes along the CTA’s Green and Red Lines.
Photography is permitted at many participating locations, and organizers are encouraging visitors to share their discoveries through the Open House Chicago Photo Competition.
