Pre-Historic Sites - B.C.
         

For reasons apparently completely unknown, earlier civilizations erected standing stones,
circles of standing stones, burial mounds, and other stone edifices. They left no written histories
so the use of structures other than burial mounds and crypts, remains hidden.
