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 Platteville’s 147 sits above most of its state (96% of Wisconsin towns have fewer) while its 169 historic buildings outnumber those of 92% of U.S. towns.

What stands out about Platteville’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Platteville was settled by pioneers and early lead miners; along inlets and flat groves of The Rountree Branch and Little Platte River. Part of the Platte River shed; these rivers flow into the greater Upper Mississippi River system. More specifically located in the Driftless Region of Southwestern Wisconsin. Due to its geographic location; areas of town are carved by ridges, narrow valleys, and steep hills. The influence of geography can also be seen in the irregularity of the streets in the community. As the town grew, roads were given odd routes, to avoid the steep ravines and mining shafts strewn about the locality.
