History
Rockwall County was created in 1873. It was formed from parts of Kaufman County. People living in the area found it hard to get to the county seat in Kaufman. So, they decided to form their own county.
The county was named after its main city, Rockwall. The area is also famous for a large, natural rock wall formation. This "great rock wall" is not visible to the public today.
