A 300-year old colonial past laced with an unflinching freedom spirit pulsates through every inch of San Antonio's present-day fabric. One of the oldest European settlements in Texas, San Antonio continues to be a popular destination for tourists to the state. Originally inhabited by the Payaya tribe, the region was claimed by Spain in 1691 on St. Anthony of Padua's feast day, giving the area its name. A missionary by the name of Father Antonio de Olivares visited the site in 1709 and lobbied for a mission and settlement on the spot. After a lengthy planning process, Misión de San Antonio de Valero, more famously known as the Alamo, was finished in 1718. In 1836, American settlers clashed with the Mexican army, resulting in the famous Battle of the Alamo, which is commemorated today with an interactive museum within the old complex. San Antonio is one of Texas's most visited cities, both for this profoundly iconic building and for the lovely River Walk which takes pedestrians along the length of the San Antonio River.
