The Woolworth Building's lobby is one of the most extravagant interiors in New York — gilded, vaulted, and normally off-limits without a paid tour. Opening the weekend there is a statement about what the whole festival is for, and it is the only OHNY event where you get a building and a party at once.
What to expect
An evening launch event inside the Woolworth Building the night before OHNY Weekend's site openings begin.
