Discover historical landmarks and hidden architectural gems with self-guided tours exploring 30 themed neighborhood “trails” such as the new Obamas in Hyde Park to tracing the path of the Great Chicago Fire on its 150th anniversary via the free Open House Chicago app that launched last Friday. These self-guided tours are part of Chicago Architecture Center’s Open House Chicago 2021, offering its popular in-person, indoor site visits, providing rare behind-the-scenes access to more than 100 venues and over 30 Chicago neighborhoods and select suburbs. OHC participants will be able discover curated experiences at their leisure, and learn more about buildings and sites of interest in each neighborhood, thanks to the ‘Explore like a Local’ section that includes additional recommendations for places to eat, shop and visit within our participating neighborhoods. New trails in the app include: Obamas in Hyde Park, Great Chicago Fire, Helmut Jahn, Uptown Entertainment District, Hutchinson Street Historic District and Preservation Across Chicago. Open House Chicago in-person returns on Saturday, Oct. 16th and Sunday, Oct. 17th. For general information or for in-person sites and tours, visit www.openhousechicago.org.
