Sign points the way to a City Hall complex.Rockwall was founded in 1854 and is the County Seat of Rockwall County. Rockwall is approximately 22 miles east of downtown Dallas on Interstate 30 with a population of just over 25,000. Rockwall has an advantage of being near the Dallas Metroplex without losing its rural atmosphere. Rockwall has the distinction of being the smallest county in Texas but one of the fastest growing counties in the United States . The history behind Rockwall's name is filled with great speculation. While trying to dig water wells in 1851, settlers discovered an underground rock wall. Because of its man-made appearance, there has been much discussion about how the wall came into existence. Settlers believed it was a man-made barrier defining territory. Geologists believe it is the result of weather sand dikes formed along the Balcones Fault line. There is still evidence of the rock wall system which out crops at several points within the county.
