One weekend. 20+ Chicago neighborhoods. 170+ places to explore.

Open the door to architectural gems all over Chicago. Every October, the Chicago Architecture Center hosts one of the largest architecture events in the world — Open House Chicago.

Since 2011, this free public event has offered behind-the-scenes access to the greatest spaces and places in Chicago, including soaring skyscrapers, historic spaces, private residences, and other areas not normally open to the public. It’s the perfect opportunity to experience the diversity and history of Chicago’s unique architectural legacy.

Open House Chicago sites

Each year, participants can explore over 150 Open House Chicago sites across dozens of different neighborhoods. These include residential buildings, breweries, sacred spaces, members-only clubs, local landmarks, and more that have opened their doors for one weekend only.

Check back for the full 2025 list of Open House Chicago sites.

Exciting new sites from last year’s Open House Chicago included:

  • The Ramova Theatre in Bridgeport opened as a movie palace in 1929 and sat vacant for nearly 30 years before being restored and reopened this year as a restaurant, brewery, and concert venue.
  • Chess Studio at Willie Dixon’s Blues Heaven Foundation has played host to legendary artists who have shaped the sound of Chicago blues and beyond.
  • Al-Sadiq Mosque in the culturally rich Bronzeville neighborhood is one of the oldest mosques in the United States.
