Vilas Park Mound Group in Madison, Wisconsin, is a Native American archaeological site preserving a bird effigy, a linear mound, and six conical mounds from a once much larger ceremonial and burial landscape. Built by Mound Builder peoples between 800 and 1100 A.D. during the Late Woodland period, these earthworks served burial and cultural purposes. Development destroyed a second bird effigy and two additional conical mounds and damaged two others. Because Madison once had more than 1,000 mounds and only about 200 survived, this group is especially important for understanding Late Woodland traditions. It was listed on the National Register of Historic Places in 1991.
