The Rock Wall

In 1852, while digging a well, farmers discovered a rock wall that crossed the county. The "Great Wall of Texas" is 7 stories high and 20 miles long. Was it built by an ancient race of giants or is it an unusual natural formation? Scientists have determined that this is a natural formation, but controversy continues as many believe the wall was built by prehistoric natives.

When the town of Rockwall was formed, it was named for the rock formation.
