Think you know New York City? You might be surprised by just how much of the city is hiding in plain sight!
Behind those familiar facades, tucked-away gardens, historic buildings, grand landmarks, and seemingly ordinary doors are hundreds of spaces that most New Yorkers never get the chance to step inside. But for one very special weekend this fall, some of the city’s best-kept secrets are opening up.
Open House New York Weekend is returning October 16–18, giving curious New Yorkers the chance to explore more than 300 sites across all five boroughs—including places that aren’t typically open to the public. From getting a closer look at the Flatiron Building at dusk to wandering through the Rockefeller Center Gardens and exploring the historic Brooklyn Army Terminal, there’s plenty to discover.
Has there ever been a better excuse to play tourist in your own city? Whether you’re a lifelong New Yorker or simply love finding the stories and spaces hiding behind the city’s most familiar streets, this is one fall weekend worth keeping on your radar.
