The Cutchogue New Suffolk Historical Society is a non-profit organization that owns and maintains the Old Burying Ground and the historic structures — one of which was originally built by European settlers in 1649 — located in the hamlet's Village Green. The group is run in large part by volunteers and is chartered by the New York State Educational Department Board of Regents as an educational institution. Staff members give tours of the historic structures and help coordinate seasonal activities including month-long Christmas festivities in December.
