Mission Nuestra Señora de la Purísima Concepción de Acuña (Mission Concepción)

Mission Concepción was established in the early 18th century and moved to its present San Antonio site in 1731. The mission church retains original 18th-century stonework and painted frescoes and is frequently cited as the oldest unrestored stone church in the continental United States. Mission Concepción is part of the San Antonio Missions National Historical Park and is included in the San Antonio Missions UNESCO World Heritage Site.
