Six hours southeast of Atlanta off the Georgia coast on Sapelo Island, archaeologists have unearthed the remains of an ancient walled city which predates the construction of Egypt’s pyramids. Known as theSapelo Shell Ring Complex, this ancient city was constructed around 2300 B.C. and featured three neighborhoods each surrounded by circular walls twenty feet in height constructed from tons of seashells. Some of the earliest pottery in North America was also found buried in the remains of this lost city.
