San Antonio, Texas is a culturally rich and historically significant city in south-central Texas, known as the second-most populous city in the state. Founded in 1718 as a Spanish mission and colonial outpost, it later became the site of the iconic Battle of the Alamo during Texas’s fight for independence. Today, San Antonio blends its deep Hispanic heritage with modern growth, serving as a major military hub and a top tourist destination thanks to landmarks like the River Walk, historic missions, and vibrant festivals.
