Man Mound

The Man Mound is a prehistoric humanoid earthwork located in Greenfield, Sauk County, Wisconsin, east of the city of Baraboo. Constructed during the Late Woodland period, the mound is the only surviving anthropomorphic effigy mound in North America. The mound depicts a horned humanoid figure and may have held religious or ceremonial significance to its builders. The mound was preserved as a county park in 1908, listed on the National Register of Historic Places in 1978^[2] and designated a National Historic Landmark in 2016.
