The Library of Congress has recently scanned and mounted Sanborn maps of Golden. 3 sets are available -- 1886, 1890, 1895. Sanborn was a fire insurance company. They produced very detailed maps of cities in order to determine how much fire insurance should cost. The company produced maps for thousands of towns and cities throughout the the United States. The maps show the dimensions on the buildings, note what the buildings are made of, the names of the companies that occupy the building, and often the owner's name. The Sanborn maps are a historical treasure. View with fascination!!!
