The heritage at the Angel Mounds State Historic Site stretches back about 1,000 years. Around 1000 AD, a group of Native Americans began building a town along the Ohio River. The land was chosen because the river offered protection with the river on one side and a slough on the opposing side. The community built large platform mounds, defensive palisades, and numerous dwellings. Angel Mounds is a great example of the Mississippian Culture.
