Discover Aztalan
Aztalan State Park preserves one of Wisconsin's most remarkable archaeological treasures โ a Mississippian culture site occupied roughly 900โ1300 CE, with connections stretching from the Great Lakes to the Gulf Coast.
Three major platform mounds dominate the landscape โ earthen monuments built by hand over centuries. These structures served as ceremonial platforms, elite residences, and symbols of political power in the Mississippian world.

A reconstructed wooden palisade wall with bastions encircles much of the ancient settlement. Built in 1968 using original post holes, it evokes the defensive architecture that once protected this thriving community on the banks of the Crawfish River.
