||Built by the Franciscan friars in 1731, the stone aqueduct was used to carry the water from the San Antonio River to irrigate the lands in the vicinity of Mission San Francisco de la Espada. The aqueduct is still in an excellent state of preservation and still in use after more than 200 years. The massive round arches that span the Piedras Pintas Creek, though only a few feet high, resemble the arches of the Roman aqueducts built by the Caesars. It is only structure of its kind in this locally that remains today. It is said to be the only aqueduct of its kind in the United States.
A park has been developed by the San Antonio Conservation Society to provide a proper setting for this small monument to the faith and ingenuity of man. A stone house on the property is known to date from the Spanish era.
