One of the most intriguing granite monuments ever erected stands in Elbert County , near the South Carolina border. The Georgia Guidestones dominate the highest elevation in the county, which is located in the northeastern Piedmont section of the state. Known to some as the American Stonehenge because of their striking resemblance to England's famous monument, the Georgia Guidestones were unveiled on March 22, 1980.

Like ancient Stonehenge, the modern Guidestones serve as a celestial clock of sorts, recording the passage of time through special features. Unlike Stonehenge, however, the Guidestones contain a written message for humanity. The general layouts of the two sites are also different from one other. While Stonehenge is arranged in a circular manner, the Guidestones are positioned in an "X" pattern, with each line of the axis oriented toward specific areas of the moon's annual rotation around the Earth.

The Guidestones' mysterious origins go back to the summer of 1979, when a man calling himself R. C. Christian came to Elberton in search of both a granite firm to execute his design for a monument and a suitable site for the construction of it. The man admitted that "Christian" was a pseudonym, chosen because it represented his own beliefs and those of the organization that planned and funded the project. To this day, Christian's real name and the true identity of his organization are unknown. Christian claimed that he chose Elbert County because of its abundant supply of granite, the rural nature of its landscape, and its relatively mild climate, and because some of his ancestors had once lived in the region.

Georgia Guidestones Joe H. Fendley Sr., president of the Elberton Granite Finishing Company, was initially shocked when Christian first explained his plan to build a gigantic granite monument inscribed with wisdom for the ages—suggestions or directions that would lead humanity into an "age of reason." Christian also informed Wyatt C. Martin, president of Granite City Bank, of his hope that other conservation-minded groups in the country would later erect even more stones to form an outer ring around the central structure. He told Martin that he wanted the monument to be erected in a rural area, away from crowds and tourists.

Meanwhile, Fendley put his laborers to work on the structure, which consisted of four massive blue granite slabs, one center stone (known as the Gnomen stone), and a capstone. When finally completed, the monolithic structure weighed 119 tons and contained 951 cubic feet of granite. The structure also supported more than 4,000 sandblasted characters and letters, each averaging about four inches in height. Christian and Martin selected a five-acre plot in the middle of a cow pasture, approximately seven miles north of Elberton and eight miles south of Hartwell , with a commanding view to the east and the west, on which to build the monument. The area chosen was in close proximity to what the Cherokee Indians called "Al-yeh-li A lo-Hee,"—the center of the world. The land on which the Guidestones stand is owned by Elbert County.

Georgia Guidestones Theinscriptions on the Guidestones are meant for current and future generations. Sandblasted along the square capstone sitting atop the structure is the basic message: "Let these be guidestones to an age of reason," in Babylonian cuneiform, Egyptian hieroglyphics, Sanskrit, and classical Greek. The four granite slabs, each weighing 42,137 pounds and standing more than sixteen feet in height, list ten "guides" for mankind in eight different languages. The languages represented on the four major stones are Arabic, Chinese, English, Hebrew, Hindi, Russian, Spanish, and Swahili. The engraved messages can be subdivided into four major areas: governance and the establishment of a world government, population and reproduction control, the environment and humankind's relationship to nature, and spirituality.

While some of the "guides" are self-explanatory, others are open to discussion and interpretation. The rich variety of interpretations evoked by the Guidestones has likewise caused much controversy and debate to swirl around the hidden or intended meanings of the messages. According to the Guidestones, the following ten principles are offered to ensure humankind's future survival:

1. Maintain humanity under 500,000,000 in perpetual balance with nature.

2. Guide reproduction wisely — improving fitness and diversity.

3. Unite humanity with a living new language.

4. Rule Passion — Faith — Tradition — and all things with tempered reason.

5. Protect people and nations with fair laws and just courts.

6. Let all nations rule internally resolving external disputes in a world court.

7. Avoid petty laws and useless officials.

8. Balance personal rights with social duties.

9. Prize truth — beauty — love — seeking harmony with the infinite.

10. Be not a cancer on the earth — Leave room for nature — Leave room for nature.

Astronomical phenomena are also associated with the Guidestones. The four large upright granite slabs that compose the face of the structure are oriented to the limits of the moon's migration during the course of the year. An eye-level, oblique hole is drilled in the Gnomen stone upward toward the celestial heavens and oriented on Polaris, the North Star. In the middle of the Gnomen stone is a large slot with a hole cut through the granite, orienting the monument with summer and winter solstices. The Guidestones also act as an enormous sundial. Drilled through the capstone is a seven-eighths-inch hole, which allows sunlight to shine on the southern face of the Gnomen stone at noon.

The Elberton Granite Museum, in Elberton, offers an impressive display model of the Guidestones as well as a short film detailing its construction. The museum also provides free informational brochures about the Guidestones and their creation.
