Are guidestones on public or private land?
In June 1979, a man using the pseudonym Robert C. Christian approached the Elberton Granite Finishing Company on behalf of “a small group of loyal Americans”, and commissioned the structure. Christian explained that the stones would function as a compass, calendar, and clock, and should be capable of “withstanding catastrophic events”.
On March 22, 1980, the monument was unveiled before an audience variously described as 100[6] or 400 people.[2] Christian later transferred ownership of the land and the guidestones to Elbert County.
