Fort Terry, Coastal defense fort on Plum Island, New York.
The fortification includes eleven gun batteries positioned along the coastline, with underground bunkers connected by a narrow-gauge railroad system built in 1914.
The United States government acquired this land in 1897 to establish Fort Terry as part of the defense network protecting the eastern entrance to Long Island Sound.
The Corchaug and Montaukett Native American tribes exchanged Plum Island for a coat, a barrel of biscuits, and 100 fishhooks before European settlement.
Visitors can reach the former military installation through Orient Point, where ferries transport researchers and personnel to the current research facility.
The fort changed its purpose from military defense to animal disease research in 1954, becoming the Plum Island Animal Disease Center.
