Moundbuilder Indian Mounds and Earthworks


Ohio is the largest physical serpent effigy mound in the world. While there are several burial mounds around the Serpent mound site, the monument itself does not contain any human remains and the structure itself is therefore now primarily recognised as an astronomical observatory. The Serpent was recently named by National Geographic as one of the four �Sacred Places of the World� and is also a U.S. nominee to the UNESCO World Heritage sites.


Of all the prehistoric American mounds that have survived the test of time, the serpent mound is one of the most intriguing. In addition to the presence of the mound itself and the debate over the meaning of the ‘egg’ feature in its mouth, it was built overlooking a massive impact crater, which adds more myth than answers to the legend of the Great Serpent Mound.

The Serpent varies in height from less than a foot at its spiral beginning to more than three feet at its highest points. The serpent winds back and forth for more than eight hundred feet and seven coils, and ends in a triple-coiled tail. The serpent head has an open mouth extending around the east end of a 120-foot (37 m) long hollow oval feature.

This oval is said to possibly symbolize several things: A primordial egg, the sun, the body of a frog, the universe or merely the remnant of a platform. Of course, it is not conclusively known what its purpose is, but that only adds to its beautiful mystery.

The Great Serpent Mound is a 1,348-foot (411 m)-long, three-foot-high prehistoric effigy mound.

It is not known which culture exactly is responsible for the original construction of this magnificent Mound, but there are several clues we can use to deduce its makers. It is clear that many different cultures adapted this structure for their own needs, but who created it.?

Researchers have attributed construction of the mound to three different prehistoric indigenous cultures. Although it was once thought to be Adena in origin, now based on the use of more advanced technology, including carbon dating and evidence from 1996 studies, many scholars now believe that members of the Fort Ancient culture built it about 1070 CE (plus or minus 70 years).
