Thomas Point Shoal Located just north of the mouth of the south river, south of Annapolis. It is probably the most recognized lighthouse in the chesapeake bay. It is the only screw-pile type light on the bay in it's original position and is the 3rd light used to mark the shoal. Thomas Point was commissioned in November 1875. Heavy rip rap has been placed around the light to fend off ice. The lighthouse was manned until 1986 and was the lighthouse on the bay to be fully automated. It has a bright red roof white sides. It is so well maintained and in such perfect condition- like it is waiting for its keeper to return.
