Every year, Open House New York weekend is one of our readers’ favorite events, allowing them access into hard-to-visit sites and to take in unique programming in others. While the full list of sites won’t be released until early October, we’ve partnered up with OHNY to curate this feature of special locations you shouldn’t miss in this year’s lineup, selected especially for Untapped Cities readers.

This year’s Open House New York, which will take place on October 17th and 18th, will be more “open” than ever, with many locations (and all the ones featured below) now accessible through Open Access, meaning no need to battle for those advance reservations. Stay tuned for an additional guide we will publish, also in partnership with OHNY, on the special programs this year, “Engineering New York” and “Final Mile: Food Systems of New York.” 

Late Addition: TWA Flight Center

As a late addition, Open House New York just lately confirmed that the TWA Flight Centerr will be open on Sunday, October 18th from 11 am to 3pm. The organization writes that it is “likely to be last time the TWA Flight Center will be open to the public in its current form” as a 75-year lease agreement to transform the Eero Saarinen terminal was recently approved. Check out our behind-the-scenes photographs inside this terminal to see what you’ll discover on your visit.
