Philadelphia Naval Asylum
The Philadelphia Naval Asylum is a complex of buildings at Gray's Ferry Avenue in Philadelphia, Pennsylvania. Built in 1827 as a hospital, it later housed the Philadelphia Naval School, served as a home for retired sailors for the United States Navy from 1834 to 1976, and was ultimately redeveloped as luxury condominiums. The site was placed on the National Register of Historic Places and designated a National Historic Landmark in 1971, primarily for its architecture. Set on more than , the campus includes three buildings designed by architect William Strickland that are considered some of the best  examples of Greek Revival architecture in the United States: Biddle Hall (the 1833 main building), the surgeon's residence and the governor's residence. For seven years, from 1838 until 1845, the campus housed the Philadelphia Naval School, a precursor to the United States Naval Academy. Beginning in 1838, midshipmen approaching examinations for promotion were assigned to the school for eight months of study. In 1842, William Chauvenet was placed in charge of the school and formalized much of the study. When the Naval Academy was formed in 1845, four of the seven faculty members came from the Philadelphia school . On July 1, 1889, its name was changed to Naval Home. In 1976, the Naval Home was moved to Gulfport, Mississippi, after it was determined that the Philadelphia facility could not be economically expanded and modernized. In 1988, the property was sold to residential developer Toll Brothers. The main building was damaged by arsonists in 2003. It has since been restored as luxury condominiums.
