Mayor Bill de Blasio and First Lady Chirlane McCray are planning to open Gracie Manson to children on Oct. 28 for a Halloween celebration.
Festivities at the historic mansion, built in 1799, include a "spooky walk" through the home, then trick-or-treating at the front door.
Both de Blasio and McCray are planning to dress up, and attendees are asked to bring non-perishable foods for a food drive for City Harvest.
There are no spaces left for the free event, though those interested can sign up for the waiting list at on.nyc.gov/1ziu7H9.
