Ancient pyramid in Tennessee

Native American Pyramid Sits Hidden

Archaeologist:  State Looks To Provide More Access To Historic Sites"It was a fabulous site. We're looking at a city on celebration days, equinox days, that there could have been 5,000 to 8,000 Native Americans here from all over the area," said Mark Tolley of the Ancient Sites Conservancy.

For 500 years, the site was one of the most important ancient Native American villages in Tennessee.

"The big temple mound is a four-sided truncated pyramid. That means it's flat on the top, and there was a structure there," said Tolley.
