Founded in 1731, Mission Concepcion is part of the San Antonio Missions National Historic Park — which also includes Mission San Jose, Mission San Juan and Mission Espada. This historically significant mission was the site of the Battle of Concepcion, which occurred in 1835 and was fought between Mexican troops and Texas insurgents led by James Bowie. This battle is considered by many to have been the first significant skirmish of the Texas Revolution.
Today, Mission Concepcion, which is the oldest unrestored stone church in the United States, is still an active Catholic parish. Sunday mass has been held in this church uninterrupted since it was founded.
