The annual event opens the doors of typically off-limit spaces during its festival running from October 17 through 19. This year, more than 300 sites are on the roster, including an exclusive rooftop garden in Rockefeller Center, a city compost facility, an Ellis Island boat and a private gallery in the World Trade Center.
