At the mouth of the Delaware Bay estuary at Lewes, most of the district is offshore, but it also includes land housing the former US Coast Guard station.
This Breakwater Harbor Historic District was added to the National Register of Historic Places in 1989. The US Congress first commissioned a study in 1822 to explore the feasibility of creating the safe shipping haven at what would become Breakwater Harbor. The result was a recommendation for a permanent harbor. Today, the Lewes Coast Guard Station is the Delaware River pilots' station. The 1938 balloon-framed Coast Guard building faces Breakwater Harbor.
