14. Presidio San Antonio de Béxar (Texas)
Founded in 1718, Presidio San Antonio de Béxar served as a Spanish military stronghold and the seed from which modern San Antonio would grow. This outpost witnessed shifting loyalties and cultures as Spanish, Mexican, and Anglo settlers shaped the region. Its long, layered history culminated in the dramatic events of the Texas Revolution. Today, traces of the presidio remain, reminding visitors of the complex frontier heritage that shaped both Texas and the broader American story.
