Sentinel in New York Harbor

Governors Island was one of the longest continuously active military posts in the United States. Since the late 1700s the island has served as a major Army headquarters and later as the largest Coast Guard base in the nation. Its military role ended in 1996 after over 200 years of service.

The story began with the construction of Fort Jay and Castle Williams, which were part of the network of forts protecting New York Harbor. At the time Castle Williams was constructed shortly before the War of 1812, these imposing stone fortifications were state-of-the-art, but advances in weaponry rendered them obsolete by the 1830s. Their survival as two of the best preserved coastal fortifications of that period was due to the continuous presence of the military and the important role the island played over two centuries.

The military legacy of Governors Island lies not only in the island's physical structures, but also in the stories of those who worked to promote the security and values of our nation here and abroad. One such individual was Secretary of War Elihu Root who, while enlarging the island for Army support functions in 1901, recognized the historic significance of Fort Jay and Castle Williams and saved them from demolition. The island's heritage also includes the accounts of soldiers who temporarily called the island home while mustered here before being deployed to faraway battlegrounds like Mexico in 1846 and the Normandy beachheads during World War II.

The history includes the experience of Confederate prisoners crowded into Castle Williams during the Civil War, and their 20th-century counterparts incarcerated in the old fort, which had become part of the army prison system. Governors Island preserves the stories of personal achievements like the first successful flight over water. In 1909 Wilbur Wright took off from the island's dusty parade ground and flew around the waist of the Statue of Liberty. Over time this early airstrip would serve as an airfield, polo ground, and warehouse depot.

Though retired from active duty, Governors Island has again been called to serve, this time for public enjoyment and discovery. In 2001 Governors Island National Monument was established to preserve Fort Jay, Castle Williams, and the setting for over two centuries of military life.

A Brief History of Governors Island

New York Harbor's abundant waters and lands first attracted American Indian peoples like the Lenape. Dutch settlers in the 1620s took advantage of the diverse ecosystem and established maritime enterprises. The British noted the harbor's strategic potential and, by 1674, secured it for the Crown.

In 1776 Gen. George Washington's colonial army made a valiant attempt to fend off the British siege of New York. Patriot cannons on Governors Island fired some of the first shots of the Battle of Brooklyn. The British prevailed and held New York for the duration of the Revolutionary War, but the experience steeled the resolve of the young nation to protect its harbors.

In one of its first initiatives that was truly national in scope, the United States began in the 1790s to fortify important harbors with a series of coastal defenses. Fort Jay and Castle Williams represent this early national effort. By the War of 1812, New York Harbor's installations proved effective deterrents to the British Navy.

As the early forts became obsolete, most were converted to other uses. Governors Island remained in service as a U.S. Army administrative and training center. In 1878 the island, once considered an outpost, became the Army's headquarters for the eastern United States, and after World War II, the First U.S. Army was headquartered here.

As New York City gained in international importance, so did the prestige of a posting to Governors Island. For army officers, it was recognition of accomplishment and a test of leadership that often led to more senior commands. Soldiers stationed here enjoyed social, political, and business connections in the city rivaled by few other posts.

On June 30, 1966, the Army left the island and the U.S. Coast Guard established the headquarters for its Atlantic Area Command—its largest base in the nation. For 30 years the Coast Guard and their families enjoyed the same sense of community and military prestige as their predecessors, a touch of small town life in America's largest city.
