Castolon is a small trading and farming community in far southwest Texas. Set beneath the towering cliffs of the Sierra Ponce, the lack of steady rain makes for an inhospitable climate. This panorama shows three of the adobe buildings which were built in 1919 and used to house the first La Harmonia store. The La Harmonia store stocked a variety of merchandise, catering to farmers and ranchers on both sides of the Rio Grande. When the U.S. Army troops departed in 1921, the store was relocated to its present location in the troop barracks.
