Nassau County acquired the Powell property and began to populate it with the endangered homes and barns. On some 200 acres of rolling hills, more than 55 historic buildings -- all original structures saved from destruction and moved to the site - provide the setting for costumed interpreters to portray farmers, teachers, store keepers, blacksmiths and the others who made up a community of the mid-1800's. While on the subject of history, note that the Vanderbilt Motor Parkway ran a few yards north of GZ and one of the bridges is 200 yards northeast.
Directions: Get onto Spagnoli Road in Old Bethpage and look for a facility where people can "safely ice skate" on the north side the road. Park in the northwest corner of the L-shaped parking lot and head in on foot, northwest to GZ. These woods are a buffer between the Spagnoli Road businesses and the Old Bethpage Village Restoration.
