Fort DuPont

Fort DuPont is a former military installation spanning 350 acres along the Delaware River with over 75 buildings and earthen fortifications. The site contains structures from different periods, with some showing Colonial Revival architectural details and others demonstrating military engineering from various eras.

The fort was constructed starting in the 1860s as a defensive installation and later became a mobilization center during World War II. During that conflict, the site held a detention facility for captured enemy soldiers.

A local baseball club plays vintage games on the grounds using nineteenth-century rules and equipment. You can watch these matches as part of the living heritage that visitors experience here.

The grounds are walkable with paths connecting the various buildings and fortified areas throughout the site. Plan for several hours to explore the extensive grounds at a comfortable pace.

A resident curator program allows individuals to restore historic buildings while living on the property through long-term agreements. This approach keeps the structures occupied and actively maintained while preserving military heritage.
