7. Gramercy Park Used to Be Open to the Public on One Day of the Year

Once upon a time, Gramercy Park was open to the public on Gramercy Day, which usually fell on the first Saturday in May. In 2007, however, the trustees of the site stopped opening its gates because the event turned into “a street fair.” Today, the private space is only accessible to the public on Christmas Eve; a Christmas tree will be erected there during the holiday season.
