Marathon County maps all Wisconsin maps

Meticulously detailed, color-keyed street maps created for all sizes of cities and villages, Sanborn Maps helped insurance agents in the late 19th and early 20th centuries determine the degree of fire hazard associated with a particular property. Most maps date between 1883 and 1930. Physical maps are held at MCPL Wausau, but online versions are accessible via the Wisconsin Historical Society using the provided links.
