Espada Acequia, also known as the Piedras Creek Aqueduct was built in 1731 to supply Mission Espada with potable water and irrigation. Mission Espada is one of five existing missions along the San Antonio River. Built by Spaniards to support their quest for exploration from New Spain (present day Mexico), they eventually became centers for spreading the Catholic faith to frontier Indians. The five missions within the San Antonio Missions National Historical Park flourished between 1747 and 1775, but still experienced raids by local Comanche and Apache Indians. Mission Espada is the only mission of the five that has continued to serve its surrounding community to this day.
