More than 1,200 years ago, a group of ancestral Caddo built a village and ceremonial center here. Today, three earthen mounds, still considered sacred to Caddo people, rise from the lush Piney Woods landscape. Learn how the Caddo lived on the land through exhibits and programs.

Historic Road Trip: Nacogdoches and San Augustine

Known as the “Oldest Town in Texas,” Nacogdoches takes immense pride in its history. In fact, the entire downtown is listed in the National Register of Historic Places. Nacogdoches honors its heritage through a statue of the city’s founder, Gil Y’Barbo, and numerous historical museums, each conserving a different part of the town’s 241-year legacy. In reality, its settlement is much older—Caddo Indians arrived in this area 10,000 years prior to the city’s establishment.
