Constitution Island is located along the eastern shore of the Hudson River, across from West Point and south of Cold Spring. It is part of the United States Military Academy, a National Registered Landmark. The Warner House and ruins of the Revolutionary War fortifications are the points of interest. Gen. George Washington was appointed by the Continental Congress to work with the New York Provincial Congress to make plans on how the Hudson River should be fortified against the British. When Sir Henry Clinton s British troops went up the Hudson River from New York City in 1777, the small group of American soldiers encamped on the island destroyed as much as possible of the unfinished fort and fled.
