It is the county seat of Rockwall County. Rockwall County is the second wealthiest county in the state of Texas in terms of median income. The majority of its residents enjoy a relatively high standard of living. The name Rockwall is derived from a naturally jointed geological formation, which has the appearance of an artificial wall.
The area of Rockwall was originally occupied by Caddo Indians. Creek Indians moved to the area in early 19th century. The origin of Rockwall also is related to the selection of its name. 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. The current mayor is David Sweet.
