An origin story speculates that the Indian mounds were built by an ancient civilization called Adena.

The Adena people are considered an ancient native society. They are classified as Mound Builders. They are believed to have lived in the Ohio River Valley 400 years ago b.c.

Although this is a very old civilization, much research has been done on the Adenas. It is currently known that:

  • They were hunters and gatherers.
  • They had several villages spread across the Ohio River Valley.
  • They build mounds for religious celebrations, but they also build mounds for protection and for funerary purposes.
