The association of Paleo-Indian artifacts with extinct Pleistocene mammalremains in various archeological sites within in the Texas Prairie-Savannah Region of eastern North Central Texas, including a site in Collin County andClovis points recovered from the Brushy Creek Clovis Site in Hunt County, demonstrates that Rockwall region was occupied by prehistoric Native American cultures at least as far back as 13,500 to 13,000 years ago.More recently, the Rockwall region was occupied by Caddo Indians. CreekIndians moved to the area in early 19th century.
In 1851, as the first Anglo-American settlers moved to the area, they started to dig wells. During the digging, they found large underground rock walls that were initially believed to be manmade. Later study of the wall-like features by geologists and archaeologists found them to be jointed, natural sandstone dikes that had intruded Cretaceous marl.
The town was established April 17, 1854 and named after these natural rock walls. While originally part of Kaufman County, in 1873, Rockwall County was formed with Rockwall being the county seat.
