Visit San Antonio
One of the most populous cities in the United States, San Antonio is an urban oasis with plenty of history packed into its streets. Named for Saint Anthony by its Spanish missionary founders, San Antonio was the first chartered civil settlement in what would become present day Texas. First part of the Spanish Empire and later the Mexican Republic, this Texan metropolis is home to some of the most widely known Texan historical sites.
If you’ve heard the phrase "Remember the Alamo," you may have been keen to create your own memories with a visit. The Alamo was built by Spanish missionaries in the early 1700s (flooding and other issues precipitated several moves until its current location was settled). However, the Alamo is best known for the 1836 Battle of the Alamo, during the Texas Revolution. The battle wiped out a small number of Texian soldiers who had managed to hold the fort for several months. When you visit, you can learn the long, storied history of the Alamo and the other four missions that comprise this UNESCO World Heritage Site.
