Five miles southwest of downtown San Antonio lies the remnants of a once-independent town known as South San Antonio, or 'South San.' Established around 1916, the area flourished as a stop along the Texas and New Orleans Railroad and was home to hundreds of residents, including many employees of nearby Duncan Field. Though the town was annexed by San Antonio in 1944, traces of its unique past remain visible today, including buildings along West Southcross Boulevard and local landmarks like the SAS General Store and Factory Outlet.

Why it matters

The annexation of South San Antonio reflects a common pattern of urban expansion in the 20th century, where smaller communities were absorbed into larger metropolitan areas. While the town's independent identity was lost, remnants of its history continue to shape the character of the neighborhood, offering a tangible connection to a distinct chapter in San Antonio's past.

The details

South San Antonio flourished as a stop along the Texas and New Orleans Railroad, growing to include a post office and hundreds of residents by 1919. In the 1920s and 1930s, the town served as a home for many employees of nearby Duncan Field, a division of Kelly Field. By the 1930s, the population of South San Antonio had reached 3,800, but in 1944, the town was annexed by San Antonio, becoming part of the larger city. Despite this, traces of its unique past remain visible today, including buildings along West Southcross Boulevard and local landmarks like the SAS General Store and Factory Outlet, which was established in 1976 and maintains a vintage aesthetic.
