Approximately 2500 years ago, Indigenous cultures began constructing burial mounds, a handful of which still exist today. In Racine County, evidence of this Effigy Mound Culture has been discovered in areas of Racine, Raymond, and Burlington. The Racine mounds were extensively studied by Philo Hoy, Dr. Increase Lapham (who drew this map), and other archaeologists. As you can see, the highest concentration of mounds was centered near Mound Cemetery. You might also notice that most of mounds were demolished as the city grew. There is no definitive answer as to why these effigy mounds were built other than as a place to bury the dead (also, not every effigy mounds contain human remains) but there are several theories. The animal shaped mounds may have been symbolic of the clans that built them. They may have been some sort of map or perhaps even something related to a calendar. There is also a theory that they may have been related to sources of water because so many can be found near lakes and rivers, such is the case with Racine's mounds.
