Wilmington (New Castle County)

Where: Delaware · approx. 39.75, -75.55 (vicinity only)

Why this spot: 1880s+ Sanborn-mapped town on Sits at the confluence of the tidal Christina and Brandywine rivers where they meet the Delaware River; old wharves, ferry landings, and shipyards lined the Christina waterfront.

What turns up: Local druggist and apothecary bottles, blob-top and Hutchinson sodas, embossed Wilmington brewery beers, stoneware crocks, clay pipe stems, cut nails, and copper coins around former riverfront wharf lots, hotel yards, and privy sites in the old commercial district.

Access: Gray area.

Delaware framing: the beds of the navigable tidal Christina and Delaware rivers below the mean high-water line are state-owned public-trust tidelands where removing historic artifacts is restricted; the riverbank uplands and townsite lots are typically private and need the landowner's permission; state law protects archaeological sites and unmarked human burials.
