Las misiones de Texas (The Missions of Texas) [PDF ebook] 

This book takes an in-depth look at the Spanish missions that once spanned the state of Texas. Some of the most striking buildings were erected and able to survive and thrive during the days of wild frontier. Interaction with Native Americans, and the role that missions played in the growth of Texas towns and cities is engagingly narrated. Frequent sidebars give readers a closer look at each mission, many of which are still standing today.
