Designated a UNESCO World Heritage site and a National Historical Park, the San Antonio Missions National Historical Park is home to four of San Antonio's five missions: Mission San Jose, Mission Concepcion, Mission San Juan, and Mission Espada (the fifth one located at The Alamo which is not part of the park) that served as part of the Spanish colonization of Texas and efforts to spread Christianity nearly 300 years ago. All four of the missions are still active Catholic churches today, so be sure to check the schedule in advance to plan your visit and keep in mind they may be closed to the public for special services, such as weddings and funerals."
