The Constitution Island Association is a Non-Profit Organization that was was founded in 1916 to preserve and protect the history and traditions of the unique American site known as 'Constitution Island.'
In 1908 Anna Warner and Mrs. Russell Sage gave Constitution Island to be "an addition to the Military Reservation of West Point and to be for the use of the United States Military Academy". The Island is most famous for the Great Chain that was placed across the Hudson during the Revolutionary War and the Warner family who lived on the Island during the 19th century. The Warner House and ruins of the Revolutionary War fortifications are the primary points of interest. The Island’s 280 acres are covered with hiking trails that are enjoyed by the Island’s visitors.
