Rooftop gardens. Design studios. Historic houses. Infrastructure tours. And more!

In 2022, OHNY Weekend welcomed over 20,000 visitors into 300 places across the five boroughs, spanning 120 neighborhoods and nearly 100 zip codes. We introduced a brand new lottery system for ticketed locations and filled over 8,000 slots across the three-day festival.

Now we are hard at work alongside our community of partners, volunteers, and supporters to deliver an even bigger and better festival on October 20-22, 2023.
