This modest structure is the main chapel of the Mission San Francisco de la Espada. This mission is noted for its aqueduct, which brings water from the San Antonio river to the mission grounds.

The description states:
MISSION SAN FRANCISCO DE LA ESPADA
San Antonio, Texas
Established in 1931, Espada has what is said to be the only intact mission fort. Nearby is an aqueduct constructed by the early missionaries and which is still in use today.
–This is one of four missions in the San Antonio Missions National Historic Park. They are all located along the San Antonio River south of the city. The Alamo is not part of this Park, but is owned by the state of Texas.
This postcard likely dates from the 1950s.
