About

Fort Miles offers a captivating journey into coastal defense history within the stunning landscapes of Cape Henlopen State Park. This former World War II military installation, nestled amidst rolling sand dunes overlooking the Atlantic Ocean, served as a crucial guardian of the Delaware Bay and vital industrial centers. Today, it’s a vibrant historical area and museum, preserving powerful stories of sacrifice, innovation, and daily life during wartime, offering a unique blend of natural beauty and compelling heritage.

The heart of Fort Miles is Battery 519, a massive 15,000-square-foot underground bunker transformed into an immersive museum experience. Visitors can explore its depths to discover a restored 12-inch gun, the poignant USS Arizona Relic, and exhibits detailing the roles of the Civil Air Patrol and local military units. Above ground, the Artillery Park showcases an impressive collection of historical weaponry, while Fire Control Tower 7 provides breathtaking panoramic views of the bay, ocean, and surrounding maritime forest, giving a sense of the strategic importance of this site. For a different kind of immersion, the Seaside Nature Center, once the fort's prison, now houses exhibit tanks with local marine life, offering a glimpse into the diverse ecosystem of the region.

Visiting Fort Miles is an unforgettable experience, combining historical exploration with the natural beauty of the Delaware coast. Whether you're peering into the past within a hidden bunker, imagining artillery fire from an observation tower, or reflecting on the serene coastal environment, the site offers rich educational opportunities and striking visual moments. It’s a place where history truly comes alive, providing insights into a critical period of American defense and a deeper appreciation for both human ingenuity and the enduring power of nature.

Fort Miles was constructed between 1939 and 1942, becoming a primary installation of the Harbor Defenses of the Delaware during World War II. Its strategic purpose was to protect the mouth of the Delaware Bay and safeguard vital East Coast industrial targets like Wilmington and Philadelphia from potential German naval attacks. At its peak, the fort was a bustling military city, housing over 2,200 soldiers and featuring more than 250 buildings, including gun emplacements, barracks, and even a Prisoner-of-War Headquarters for German and Italian captives. After World War II, Fort Miles continued as an active Army installation and served as a training post during the Korean War, later transitioning into a top-secret Navy listening post during the Cold War to monitor Soviet submarines. The fort was ultimately closed as an active military site in 1958, and much of the land was transferred to the State of Delaware by 1961, eventually becoming part of Cape Henlopen State Park. Since 2003, the Fort Miles Historical Association, in partnership with Delaware State Parks, has diligently worked to renovate, operate, and expand the museum and historical area, transforming it into the significant educational and cultural destination it is today.
