Rockwall is a city in Rockwall County, Texas, United States. It is part of the Dallas/Fort Worth Metroplex. The population was 17,976 at the 2000 census. It is the county seat of Rockwall County. The name is derived from a geological formation.
The area of Rockwall was originally occupied by Caddo Indians. Creek Indians moved to the area in early 1800s. 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 seemed to be manmade though scientist believe they are natural formations. The town was established April 17, 1854 and named after these rock walls. While originally part of Kaufman County, in 1873, Rockwall County was formed with Rockwall being the county seat.
