Sanborn Fire Insurance Maps of Wisconsin Communities

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.
