Beattie Park Mound Group

The site contains three conical mounds, one linear mound, and an effigy mound shaped like a turtle within a 7.5-acre area near Rock River.

Built between 700-1100 CE during the Late Woodland period, the mounds were part of a larger complex that originally included nine conical structures and two effigy formations.

The mound group represents ceremonial practices of Native American communities who constructed these earthen formations along the waterways of northern Illinois.

Located between Park Avenue and Mound Avenue, the site offers visitors direct access to preserved ancient structures within an urban park setting.

One remaining mound sits independently in front of a house at 509 Indian Terrace, marking the extent of this archaeological complex.
