Castroville was founded in 1844 by Henri Castro and settlers from Alsace and other parts of Europe. The resulting limestone and timber-frame architecture gives the town a visual identity unlike most Texas communities, and the historic district preserves dozens of nineteenth- and early twentieth-century structures.
The strongest first visit begins on foot. Landmark Inn, St. Louis Catholic Church, historic homes and the former county courthouse help explain the settlement pattern, while the Medina River and Castroville Regional Park add a natural counterpoint to the architecture.
Castroville works well as a full-day heritage stop from San Antonio, but an overnight stay allows a slower walking tour and more riverfront time. Festival weekends can materially change parking and lodging demand, and individual historic properties should be checked for current access before arrival.
