Constitution Island

Constitution Island sits in the Hudson River opposite the United States Military Academy, separated by water but linked to the eastern shore through Constitution Marsh. The island contains the remains of fortifications built during the American Revolution and later modified by military engineers.

The American forces first fortified the island in 1775 to defend the Hudson River during the Revolution. After British troops destroyed these defenses in 1777, engineer Thaddeus Kosciusko redesigned the fortifications using advanced military principles.

The Warner sisters made their home here during the 1800s and gained recognition as authors. They taught Bible studies to cadets from across the river, becoming influential figures in the local community.

The island is only accessible through organized tours run from West Point, typically available during summer months. Visitors should plan ahead and coordinate with West Point staff to secure a spot on a tour.

From 1778 to 1782, the island served as an anchor point for a massive iron chain stretched across the Hudson to block British warships. This underwater barrier was an engineering feat designed to control river traffic during wartime.
