Lighthouses are found in Maryland's rivers and the Chesapeake Bay. Under contract for the United States Government, John Donahoo (1786–1858) of Havre de Grace built twelve of Maryland's lighthouses.
But an old lighthouse 2 miles offshore in Chesapeake Bay could be the ultimate getaway spot. And for $15,000, you can own the 144-year-old structure near Baltimore, which has been put up for sale by federal officials.
The best way to find lighthouses for sale is via a U.S. Government lighthouse “property disposal”. These happen sporadically. When one is going on, the General Services Administration lists available lighthouses on this web page.
The last of the classic Chesapeake screwpile lighthouses still in its original location, Thomas Point Shoal Lighthouse is perhaps the most recognizable and beloved landmarks on the bay. Accessible only by boat and staffed by volunteer docents, Thomas Point is on the National Register Historic Places.
