Fotografiska Museum on Park Avenue

A celebration of everything that makes the city special, Open House New York Weekend provides rare access to noteworthy or significant places across all five boroughs. Sites that may be otherwise inaccessible the rest of year magically swing their doors open, allowing the public to peer behind the curtain. Other sites provide unrivaled tours by accomplished guides. And this year, as OHNY celebrates its 20th anniversary, there will be a mix of in-person experiences, self-guided explorations and even digital content.

We’ve seized the opportunity to discover more of the city’s hidden gems, and our guide to Open House New York Weekend will show you how you can too. This year it will be 100% free (no more reservation fees!) and there will be a new lottery system for hard-to-get spots. Mark your calendar with these important dates:

• Release of OHNY Weekend Lineup - October 6

• Reservation Day - October 13
