Serpent Mounds
Two thousand years ago, Aboriginal people gathered nearby in large settlements in spring and summer to hunt, fish and collect freshwater mussels. Here, for over three centuries, these people built mounds to bury and revere their dead. These nine mounds and other closely related sites provide an exceptionally complete record of life at that time. The mound shaped like a serpent, the only one of its kind in Canada, is over 60 metres long and almost eight metres wide. Mississauga people of this area are now the proud stewards of these ancient sites.
