It was located atop Seven Foot Knoll in the Chesapeake Bay until it was replaced by a modern navigational aid and relocated to Baltimore's Inner Harbor as a museum exhibit.

It was initially installed on a rocky shoal called Seven Foot Knoll (at 39°09′26″N 76°24′12″W / 39.1572°N 76.4034°W / 39.1572; -76.4034), in the mouth of the Patapsco River.

The northern tidal reach of this river is the Baltimore Harbor, where the now-decommissioned lighthouse has been placed as a museum exhibit.

[4] In 1988, the lighthouse was removed from Seven Foot Knoll, carried by a 1000 Ton Capacity Shearleg derrick, and placed ashore in Baltimore's Inner Harbor where it was donated to the city.

The lighthouse is a contributing element in the Baltimore National Heritage Area and part of the Historic American Engineering Record.

Steinhice took the lighthouse's small motorboat and made his way out in the direction of the tug's distress whistle where he pulled six crew members from the water.

Steinhise was awarded the Silver Lifesaving Medal for his actions in saving the lives of the stranded crew.
