Ft. Sam Houston’s Quadrangle

Fort Sam Houston was designated as a National Historic Landmark in 1975. As one of the Army's oldest installations and now part of Joint Base San Antonio. Fort Sam Houston boasts the largest collection of historic structures -- more than 900 buildings. Even more consequential than the numbers is the historical integrity of the post's different sections which represent different eras of construction. Careful preservation of these areas allows the post to live with its history, surrounded by existence of the traditions of excellence established when the first soldier arrived here in 1845.
