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.
Military of the Ottoman Empire
The origin of the Naval Academy goes back to 1773, when a naval school under the name of "Naval Engineering at Golden Horn Naval Shipyard" was founded during the reign of Sultan Mustafa III on the command of Grand Vizier and Admiral Cezayirli Gazi Hasan Pasha. François Baron de Tott, a French officer and advisor to the Ottoman military, was appointed for the establishment of a course to provide education on plane geometry and navigation. The course, attended also by civilian captains of the merchant marine, was given on board a galleon anchored at Kasimpaşa in Istanbul and lasted three months. The temporary course turned into a continuous education on land with the establishment of "Naval Mathematical College" in February 1776. With growing numbers of cadets, the college building at the naval shipyard was extended. On 22 October 1784, the college, renamed the "Imperial Naval Engineering School" (), started its education for three years in the new building. From 1795 on, the training was divided into navigation and cartography for officers of the deck, and naval architecture and shipbuilding for naval engineers. In 1838, the naval school moved into its new building in Kasımpaşa. With the beginning of the reformation efforts, the school was renamed "Naval School" () and continued to serve in Kasımpaşa for 12 years. Then, it was relocated in 1850 to Heybeliada for the last time. During the Second Constitutional Era, an upgraded education system was adapted in 1909 from the Royal Naval Academy.
