The Baltimore Harbor Light, officially Baltimore Light and historically Baltimore Harbor Lighthouse is a privately owned caisson lighthouse in the Chesapeake Bay in Maryland.[2][3][4] First lit in 1908, it sits at the mouth of the Magothy River, marking the channel which leads northwest to the opening of the Patapsco River, which then leads into the Baltimore harbor. The light is located adjacent to the mouth of the Magothy River. At the time of its construction, it was the world's tallest caisson lighthouse due to the deep sediment of its location. It was the world's first nuclear powered lighthouse for a brief time in the 1960s.
