Cape Henlopen State Park (Fort Miles)
Lewes, DE
William Penn set aside Cape Henlopen as public land in 1682, one of the first such grants in the American colonies. The U.S. Army built Fort Miles here in 1940-1942 to guard the Delaware River approach to Philadelphia and Wilmington from German U-boats, garrisoning more than 2,000 soldiers and civilians before the fort later served a Cold War Navy listening-post role. It became Cape Henlopen State Park in 1964.
