Sanborn Maps

The Sanborn Fire Insurance Maps of Indiana cities and towns can be used to trace the development of Indiana municipalities from the 1880's to the middle of the 1950's. As many as ten different editions were produced for some Indiana towns.

Sanborn maps are valuable historical tools for urban specialists, social historians, architects, geographers, genealogists, local historians, planners, environmentalists and anyone who wants to learn about the history, growth, and development of Indiana's cities, towns, and neighborhoods.

Features of the maps include: outline of each building, the size, shape and construction materials, heights and functions of structures, and location of windows and doors.

The maps also give street names, street and sidewalk widths, property boundaries, building use, and house and block numbers.
