🗺️ How to Read Your Sanborn Map
At first glance, a Sanborn Fire Insurance Map looks like a collection of colorful buildings, numbers, and strange abbreviations. But once you learn how to read one, an entire town comes to life.

Originally created to help fire insurance companies assess risk, Sanborn Maps have become one of the most valuable resources available for local history, genealogy, architecture, and historic preservation.
The Library of Congress has done an incredible job preserving these public-domain maps and making them freely available for everyone to explore. Their efforts inspired us to share the simple guide that helps others understand and appreciate these remarkable pieces of American history.
At Hometown History Maps, our goal is to help bring these incredible maps out of the archives and into homes, offices, restaurants, libraries, and businesses where they can be enjoyed every day—not just by historians, but by anyone who loves the story of the place they call home.
