Gov. Andrew Cuomo made the announcement Friday.
The New Guinea Community Site, at East Market Street, was the location of an early free black community from 1790 to 1850. The site was home to black migrants looking for work, searching for family members or attempting to flee slaveowners.
During the mid-1860s, attorney John Hackett consolidated several parcels, including those associated with the former New Guinea community, into a country estate. It was later owned by the Boy Scouts and turned into a camp and then purchased by the town in 1998.
There are more than 120,000 historic buildings, structures and sites throughout the state listed on the National Register of Historic Places.
