On July 5, 2015, the Missions of San Antonio were designated a UNESCO World Heritage site. The Franciscan missions of San Antonio are a remarkable concentration of surviving structures that are a spectacular representation of the Spanish colonial influence in the New World. The religious, economic, and technological system instituted by the friars transformed a nomadic aboriginal society into a settled one, which in turn became the basis of an ethnically diverse society that continues to influence what is today a major city.
