Wisconsin towns list more on the Register than most of the country (a typical Wisconsin town has 3.0 per 10,000 residents, the U.S. 2.4), so Cedarburg’s 32.3 sits above most of its state (86% of Wisconsin towns have fewer) while its 20 historic buildings outnumber those of 79% of U.S. towns.

What stands out about Cedarburg’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The earliest evidence of humans in the Cedarburg area is the Hilgen Spring Mound Site, located in the eastern part of the city of Cedarburg, near Cedar Creek. The site consists of three conical burial mounds constructed by early Woodland period Mound Builders. In 1968, archaeologists from the Milwaukee Public Museum found human burials and artifacts, including stone altars, arrowheads, and pottery shards, during an excavation of one of the mounds. Radiocarbon samples from the excavation date the mounds' construction to approximately 480 BCE, making it one of the oldest mound groups in the state.
