Fort Sam Houston is a U.S. Army post in San Antonio, Texas. Known colloquially as "Fort Sam," it is named for the U.S. Senator, Texas Governor, and first President of the Republic of Texas, Sam Houston.
Construction at Fort Sam Houston began in the middle 1870s under the supervision of the military commander of the Department of Texas, Major General Edward Ord, a West Point-trained army engineer. Today, as one of the Army's oldest installations, and with more than 900 buildings in its historic districts, Fort Sam Houston boasts one of the largest collection of historic military post structures. The significant contributions of Fort Sam Houston to the United States were recognized in 1975 when the post was designated as aNational Historic Landmark.
