Fort Leaton State Historic Site is a massive adobe fortress and trading post on the Rio Grande near Presidio, Presidio County, Texas, in the Big Bend region. Built around 1848 by Benjamin Leaton, this fortified compound served as a trading post on the Chihuahua Trail and is one of the largest adobe structures in Texas. Features include one of the largest adobe fortifications in Texas, museum interpreting Chihuahua Trail and border history, site dating to pre-Columbian agricultural settlement, part of the Big Bend Ranch State Park complex, and 4 miles southeast of Presidio on FM 170 (River Road).
Benjamin Leaton’s Fortress
Benjamin Leaton arrived in the Big Bend in the late 1840s and built his massive adobe compound on the site of an existing Spanish presidio and mission. The fortified structure featured walls several feet thick, interior courtyards, and rooms that could house his family, workers, and trade goods. Leaton positioned himself as the dominant trader on the Chihuahua Trail, controlling commerce between Texas and Mexico.
Centuries of Settlement
Archaeological evidence shows this location has been occupied for thousands of years. Pre-Columbian peoples farmed the Rio Grande floodplain here, followed by Spanish missionaries and soldiers who established El Presidio del Norte. Leaton built his fortress atop these earlier foundations.

Insider Tips

Frequently Asked Questions
What was the Texas-Mexico border like in the 1800s?
The Texas-Mexico border in the 1800s was a lawless frontier — Comanche raids, bandits, smugglers, and rival armies created constant violence. Trading posts like Fort Leaton served as combination stores, forts, and diplomatic posts. The border was permeable — people, goods, and cultures crossed freely. The current border infrastructure (walls, patrols, checkpoints) didn’t exist until the 20th century. The Rio Grande was a lifeline, not a barrier.
