A City with Deep, Flowing Roots
San Marcos isn’t just old — it’s ancient. The San Marcos Springs have bubbled from the Edwards Aquifer for over 12,000 years, making this one of the oldest continuously inhabited places in North America. Archaeologists have uncovered tools and artifacts from early Indigenous peoples who gathered here long before Spanish explorers arrived in the 1600s.
The springs became the heart of the community. Spanish settlers called the river San Marcos de Neve, and when Anglo settlers established a town nearby in the mid-1800s, they kept the name. San Marcos officially incorporated in 1851, and when the International-Great Northern Railroad arrived in 1880, the city began to boom.
The early 1900s brought new industry, a growing university, and a reputation as a Texas travel destination. By mid-century, Aquarena Springs put San Marcos on the national map as one of the state’s top roadside attractions — complete with glass-bottom boats, mermaid shows, and yes, the famous diving pigs.
Today, the river still defines the city — not just as a playground, but as a symbol of the clear, creative current that runs through everything here.
