Northeast of the Davy Crockett National Forest lies Caddo Mounds State Historic Site, in Alto, Texas. The site’s namesake mounds were in fact temples, built and used by the Caddo people native to the region and serve today, as in the past, where religious leaders of the Caddo Nation practice spiritual rituals and connect with their ancestors.
The Caddo built these mounds on land that would one day include the El Camino Real de Los Tejas in Alto, Texas. Their creation required the backbreaking work of digging and then hauling almost unimaginable quantities of soil. The Caddo then flattened these earthen masses with grassy material on top. Caddo peoples formed their villages around them. Archaeologists estimate that the Caddo mounds date back over 1,000 years – likely to around 800 CE.[1]
Early evidence of extensive and advanced agriculture has led some historians to call the Caddo the "first farmers" of Texas. Their economy and livelihood depended for generations on the cultivation and harvest of squash, corn maize, and beans.[2] The Caddo homeland was expansive, reaching beyond Texas into parts of Oklahoma, Louisiana, and Arkansas.[3] The Caddo mounds represented part of the Caddoan socio-political and religious hierarchy, and the villages around them were the nerve center of spiritual leadership.[4] Archeological research at Caddo Mounds has uncovered traditional Caddoan pottery, and researchers have tied different variations in the pottery artifacts, such as color, texture, and markings, to different periods in Caddo history.[5] These distinct styles of pottery link Caddo people to the sites they historically occupied.[6]
The Hasinai, a Caddo confederacy in East Texas, encountered soldiers, missionaries, and merchants as part of an expanding Spanish Empire. During the era of Spanish colonialism, Caddo mounds served as both literal and figurative defenses against missionary attempts at religious conversion and political domination. The mounds acted as both territorial barriers and spiritual structures, central to Caddoan cosmology and their creation story that involved the sun, moon, and stars. This ancestral wisdom prompted Caddo people to resist and reject the entreaties of Spanish missionaries.[7] One historian estimates that, on his route to the Red River Valley, the Spanish explorer Hernando de Soto was always in the vicinity of Caddo temple mounds—including those at Caddo Mounds State Historic Site, located along the Neches River on El Camino Real de Los Tejas.[8]
In the late 1850s, settler violence forced[MGG1] [MGG2] the Natchitoches Caddo, Kadohadacho Caddo, and Hasinai people from their respective ancestral homelands in Louisiana, Arkansas, and eastern Oklahoma and Texas.[9] The Caddo have since lived in Caddo County, Oklahoma.[10] Members of the Caddo Nation engage in regular cultural heritage events to preserve their traditions, and ongoing initiatives are working to revitalize the Caddo language, which has been threatened by population decline and forced assimilation.
Visitors who come to engage with this deep history will see some of the oldest structures in North America. Three large mounds remain in the area, one burial mound and two others used for religious activities. In the nearby area, nature-oriented visitors can take advantage of hiking, fishing, and camping opportunities at Mission Tejas State Park, as well as further lessons in local history.[11] Every year, Caddo Mounds State Historic Site hosts a Caddo Culture Day celebration on grounds near Alto, TX.

The mounds sit low on the landscape, connected by a walking trail. A segment of the Camino Real wraps around the back of the site, through a thickly treed section above a swampy bayou.
