Fort Hancock, Military fort in Sandy Hook, United States

Fort Hancock is a former coastal defense installation at the northern tip of the Sandy Hook peninsula in New Jersey. The complex includes concrete gun batteries, underground passages, and brick buildings spread across an open stretch of land.

The base was established in 1895 to protect New York Harbor from potential attacks by sea. During World War II up to 7,000 soldiers were stationed here before the facility closed in 1974.

The name honors General Winfield Scott Hancock, a senior officer in the American Civil War. Today the empty barracks and officers' houses along the streets preserve the layout of a military settlement that you can walk through.

Rangers lead tours of Battery Potter and the Mortar Battery during summer, with daily visits available between 9 AM and 5 PM. Many buildings remain closed and you walk across open terrain, so sturdy shoes and weather protection are recommended.

The underground tunnel complex, originally built to store ammunition, later served as a classified command post for the defense of New York City. In the deepest chambers you can still see ventilation systems and control panels from the Cold War era.
