Sanborn Fire Insurance maps document cities in extreme detail. Not only are the positions and shapes of buildings accurately mapped, but also rough outlines of the rooms, their construction materials, and even small details like if the building hired a night watchman. See downtown San Fracisco for example: https://oldinsurancemaps.net/viewer/san-francisco-ca/?sanbor...
