About the Park

Resting atop the Great Dune and built during World War II to protect the Delaware Bay and River from German warships, Fort Miles was a state-of-the-art coastal defense fortification. While Fort Miles never engaged an enemy target, it did produce some of the most accurate artillerists in the Army. The Navy conducted tests at Fort Miles as part of the first attempt to create a fleet defense missile and also used the fort for its secret Sound Surveillance System to track enemy submarines. Parts of the fort were used as a vacation retreat for military families. Tower 7, one of 11 World War II-era fire control towers, now provides a unique perspective of the park and surrounding area. Today, the historical area operates as a museum, artillery park and oceanfront event space.

About Fort Miles

Lying amidst rolling sand dunes at Cape Henlopen State Park, on a high bank overlooking the Atlantic Ocean, is the Fort Miles Historical Area, a former World War II military base that was a key piece of our nation's coastal defense from World War II through the early 1970’s. Today, Fort Miles is home to the Fort Miles Museum, encompassing a gun battery, six barracks buildings, a fire control tower, an orientation building, and an artillery park.

The history of Fort Miles exemplifies America’s call to action to stem the tide of war against German invasions along the Atlantic Seaboard that, at the onset of World War II, appeared virtually unstoppable. The gun batteries of Fort Miles, secret state-of-the-art installations built within the massive sand dunes of Cape Henlopen, were designed to defend against the powerful German navy.

With more than 2,500 soldiers stationed on high alert, the heavy guns, mine fields, and searchlights of Fort Miles defended the vital trade centers of Wilmington, Philadelphia, and beyond. As America moved into the cold war, the role of Fort Miles shifted to highly classified missions defending against the threat of Soviet submarine operations off our coastline.

Fort Miles is a special place for history enthusiasts, veterans, families, or anyone interested in learning about Delaware stories, Delaware heroes, and Delaware’s role in WWII. Take a guided tour, enjoy an interpretive program, visit the art gallery, take in a special event, and celebrate "The Greatest Generation."
