Established in San Antonio in 1731. May have been named for statue of St. Francis in the chapel which, according to tradition, once grapsed a sword. One of the few missions near which descenants of the Indian converts and spaniards still live, Espada is considered by some to date back to Mission San Francisco De Los Tejas, founded in East Texas in 1690. A succession moves eventually brought it here. The original buildings at Espada, the farthest south of the five missions near San Antonio, were undoubtly of adobe. A wall surrounded the church (usually called a chapel), friary, granary,and work shops. Extensive farms and pastures lay nearby. By 1745 the Indians produced grain and beans, and the missioned owned 1,150 head of cattle and 750 sheep. One of the few remaining early structures is the southeast bastion (fortified round tower), which is the only mission fort left intact in San Antonio. Its three-foot rock walls, which contain holes for cannons and muskets, support a vaulted roof. Composing Espada's once-vital waterworks are a dam (one mile north), an irriation ditch, and a fine aqueduct (near this site)--the only extant spanich aqueduct in the United States.
