Each October, Open House New York Weekend offers unparalleled access to the best of New York City’s built environment by unlocking more than 200 sites across the city for tours, talks, and exploration.

The majority of OHNY Weekend sites are open free of charge, allowing 50,000+ visitors to experience, and to be inspired by, the architecture and design that define our city. Join us on October 17-19, 2025, for the 23rd annual OHNY Weekend festival.
