Naval Square, Philadelphia
Naval Square is a gated community within the Graduate Hospital neighborhood of Philadelphia that served as the first United States Naval Academy from 1834 to 1845, when the Naval Academy formed in Annapolis. It continued as a retirement home for sailors and marines and was called the Naval Home until 1976, when the facility was relocated to Mississippi.
Fort Adams
The War Department was concerned about the political sympathies of residents in Maryland during the American Civil War, so the United States Naval Academy was moved in 1861 from Annapolis to Fort Adams. In September 1861, the academy moved to the Atlantic House Hotel in Newport and remained there for the rest of the war.
