Rockwall County is the smallest county in Texas, covering only 147 square miles. In the early 1800s, the area was occupied by Caddo Indians. The Creek Indians began to arrive and as they spread the two tribes were in conflict. When the first Anglo-Americans arrived sometime in the 1840s they found these Indian groups at war among themselves.
The National Road of the Republic of Texas was surveyed and constructed in the mid-1840s through the area that would become Rockwall County. Running northeast from the Red River to Peters Colony, near the site of present day Dallas. The cities of Rockwall and Heath were founded along this road. The first post office in the area was known as Black Hill. It was transferred to the new village of Rockwall in 1855.
The Rock Wall
In the early 1850s, farmers were digging a well and discovered a rock wall that crossed the county and at some places appeared above ground level. Scientists have determined that this is a natural formation, but folk tales continue to say that it was built by prehistoric natives. When the town of Rockwall was formed, it was named for the rock formation.
The Formation of Rockwall County
In 1836, the area was established as part of Nacogdoches County, and when Texas joined the Union in 1845, it was included in Henderson County. Kaufman County was formed in 1847, and the region now known as Rockwall County was placed in Kaufman County. Citizens thought the county seat of Kaufman was too inconvenient, and in 1873, Rockwall County was formed.
Rockwall County Today
The last half of the twentieth century has brought about major changes in this once predominately-agricultural area. Bounded on the west by Lake Ray Hubbard, it has become a very desirable residential area for the continuously growing Dallas Metropolitan area.
