Rockwall, Texas
Founded in 1854, Rockwall became the seat of Rockwall County (the smallest county in Texas) in 1874. It was named for the subterranean rock formation that has been the subject of study for years. Although there has been speculation the wall was built by prehistoric man, geologists believe the phenomenon is a finger of the Balcones Fault with the "wall" formed when geologic stress split the formation.
A scenic golf course is near Lake Ray Hubbard.
