Fort Tyler was a coastal fortification on Gardiners Point Island, a small island off Gardiners Island, in Gardiners Bay, at the eastern tip of Long Island, New York.
[1][2] The fort was constructed in 1898, during the Spanish American War, to protect Long Island from the danger of bombardment from Spanish Naval vessels.
[3] The fort was abandoned in 1920 and President Franklin Roosevelt made it a bird reserve in 1938.
During World War II, United States Naval forces used the fort as a target.
The fort may contain unexploded ordnance, so landing is prohibited.
