The Adena culture, which thrived in the Ohio Valley from around 1000 BCE to 200 CE, is known for constructing various monumental earthworks, including burial mounds, geometric earthworks, and ceremonial enclosures. Their burial mounds often served as tombs for important individuals and featured elaborate grave goods. The geometric earthworks, such as circles and effigies, may have had ceremonial or astronomical significance. These structures reflect the Adena's social organization and spiritual beliefs.
