Established in 1681, and later dedicated Corpus Christi de la Ysleta, 1690; damaged by both floods and fires, but restored and maintained in original style and now familiarly called Ysleta Mission. Oldest mission in Texas, established for Tigua Indians. When founded, the mission pueblo was south of the Rio Grande, but has been left on the Texas side by changes in the river channel. Some mission land has been in constant cultivation since 1682, over 300 years!
