Longhorn is a census-designated place in Bexar County, Texas, U.S.A. Longhorn was a company owned village or town owned by the Longhorn Cement Company created for employee housing in, what was then, way out in the country far north of San Antonio. I recall that the village had its own store, post office and baseball field. Since then San Antonio has expanded north to completely surround what was company property. The village was vacated, closed down and abandoned when the company closed.
