The towns that the Spaniards of colonial Mexico planted on their northern frontier were organized around the ideal of a close interaction between church, missionary outreach, and military.

With this selection of photos, San Antonio's Churches takes a snapshot visit back through religious development throughout the three centuries of San Antonio's history.
