About the Park

the gun battery

Named for a Civil War U.S. Naval hero, Fort DuPont was built to protect port cities along the Delaware River, like Wilmington and Philadelphia from enemy ships. When its weaponry became obsolete after World War I, Fort DuPont’s role switched primarily to training. The backbone of Fort DuPont’s coastal defense included its rifle, mortar and rapid-fire batteries that can still be seen today. A theater built in the 1930s still stands on the property, as well. The Riverview Trail is a prime spot to watch wading birds fly between Pea Patch Island and the mainland. Visitors can also see ospreys dive for fish in the river during the summer months, a variety of waterfowl in winter and bald eagles year-round.

TThe park is bounded on two sides by the scenic Delaware River and the Chesapeake and Delaware Canal. Use the boat launch to get out on the water to fish and explore the Delaware River. Click for information about fishing and fishing permits.


The River View Trail takes you alongside the Delaware River and affords a glimpse of the site's rich historic past. Six gun batteries were built at Fort DuPont during what is known as the “Endicott Period” (1898-1910), and five of them can be seen along the trail: Batteries Read and Gibson, completed in 1898; Batteries Rodney and Best, and Battery Elder, completed in 1899; and Battery Elder, completed in 1904.
