Serpent Mounds is an archaeological and funerary site at Keene in Ontario, Canada, overlooking Lake Rice in Peterborough County. It lies within Serpent Mounds Provincial Park, a provincial park that is currently non-operational and was ceded to the Hiawatha, a Mississauga tribe, who continued to use the site. It was recognized as a national historic site of Canada in 1982.
The site consists of nine distinct funerary tumuli. The largest is sinuous in shape, about 60 m long, 8 m wide and 1.8 m at its highest point. It is surrounded by eight smaller oval or round tumuli, often called “the serpent’s eggs.” Although the record classifies the site as a megalithic mound with integral stones, the wider tradition describes earthworks of piled soil rather than megaliths.
The site was first explored in the late nineteenth century by the archaeologist David Boyle. It is dated between 50 BC and 300 AD and is linked with the Point Peninsula culture, a cultural period that spread across present-day Ontario and the State of New York from 600 BC to 700 AD during the sylvicole period.
Serpent Mounds is unique in Canada. The name comes from the winding shape of the largest tumulus and the accompanying oval mounds known as the serpent’s eggs. The site appears in a list of heritage places in Peterborough County, alongside the Great Serpent Mound in Ohio, USA.

About this kind of monument
Native American earthen mounds
Eastern North America has many earthen mounds, built over several thousand years by Native American peoples. They are not megaliths, but earthworks of piled soil, and they served as graves, platforms and symbols. The Adena culture of the Early Woodland period, from 500 BCE to 100 CE and centred on Ohio, built burial mounds and shared a ceremonial system. The Hopewell tradition, a network of cultures from 100 BCE to 500 CE, exchanged goods from Lake Ontario to Florida and raised burial mounds and geometric enclosures. The Mississippian period, from the end of the tenth century to the sixteenth, brought maize farming, large towns, and platform mounds on which temples and chiefs' houses stood.
The grandest is Monks Mound at Cahokia, Illinois, the largest pre-Columbian earthwork in the Americas. Its construction began between 900 and 955 CE; it is about 30 metres high and 291 metres long including the access ramp, with a base about the size of the Great Pyramid of Giza. Effigy mounds are mounds shaped as animals or symbols; the effigy mound builders are mainly associated with 550 to 1200 CE, though radiocarbon dating puts the origin of some as far back as 320 BCE. The Great Serpent Mound in Ohio, 411 metres long and about 1.2 metres high, is the largest serpent effigy known, surveyed in 1848 by Squier and Davis.
Mounds are dated by radiocarbon dating of charcoal and by pottery; many were levelled by farming and by antiquarian digging. Nineteenth-century theories of a vanished race of Mound Builders have no support: the mounds were raised by Native American peoples.
When visiting, remember that many mounds are sacred places. Look for platform tops, the flat summits of mounds that held buildings, and for the ramps and plazas around them.
