The Espada Aqueduct is a part of the irrigation system that supplied water to the Spanish Mission Espada in San Antonio, Texas. The aqueduct was built in the mid-1700s to carry water over Piedras Creek. The Espada acequia fell into disuse in the 1880s, but was restored in 1895. It is still used today to carry water for irrigation.
