San Antonio Missions National Historical Park

San Antonio Missions National Historical Park is a National Historical Park and part of a UNESCO World Heritage Site preserving four of the five Spanish frontier missions in San Antonio, Texas, USA. These outposts were established by Catholic religious orders to spread Christianity among the local natives. These missions formed part of a colonization system that stretched across the Spanish Southwest in the 17th, 18th, and 19th centuries.

In geographic order from north to south the missions are Mission Concepción, Mission San Jose, Mission San Juan, and Mission Espada. The Espada Aqueduct, also part of the Park, is due east of Mission San Juan, across the river.
