The state has a number of colonial era missions, mostly in the Sierra Gorda region. The early ones were founded by the Augustinians and Franciscans with the aim of evangelizing of the area, but they were shut down soon after their founding by the hostility of the Chichimeca. Most were unfinished and/or destroyed. The first successful missionary in the area was Jesuit Junípero Serra because colonial authorities began to militarily control the area. The best known is Bucareli Mission in Pinal de Amoles founded in 1797. Other missions are found including Santiago de Jalpan, San Miguel Concá, Santa María del Agua de Landa, San Francisco del Valle de Tilacoal and Nuestra Señora de la Luz de Tancoyol, all established in the 1750s and 1760s. After restoration efforts between 1979 and 2002, there have been efforts to register these missions as a World Heritage Site.
