Mission Concepción - relocated 18th-century mission layout

Mission Nuestra Señora de la Purísima Concepción de Acuña was relocated to its current San Antonio site in 1731 and its extant stone church dates to 1755. The mission’s church and surrounding lands were organized under Spanish colonial surveying practices, with documented boundaries and an associated acequia irrigation network used for mission agriculture. The site along the San Antonio River preserves an 18th-century mission-era surveyed layout that has been recorded in both archival and archaeological studies.
