Harbor Defence Museum

Mission

Nestled within the heart of Fort Hamilton in Bay Ridge, Brooklyn—the Harbor Defense Museum’s mission is to preserve the history and evolution of New York City’s coastal defense systems. As the only Army Museum in New York City, the Harbor Defense Museum has acquired a fine collection of military artifacts from the Revolutionary War to World War II. Come explore new exhibits on the Battle of Brooklyn or learn how to load and fire a 19th century cannon.

History

During the first half of the 19th century, the United States was compelled to expand the fortifications protecting its harbors and strategic waterways. Built between 1825 and 1831, Fort Hamilton became part of the Third System of Fortifications built throughout New York City. Today, the Harbor Defense Museum occupies Fort Hamilton’s caponier, a freestanding bastion located within the fort’s dry moat. Both structures are on the National Registry of Historic Places.

Collections

United States Army weapons, uniforms, small arms, cannons and accoutrements from 18th century to present.
