The wards of Baltimore changed over time as population growth and annexation changed the landscape of the city. Bill LeFurgy, previous City Archivist, wrote a helpful introduction to the ward changes in his article “Baltimore Wards, 1797-1978: A Guide.” This article also includes a list of many useful maps of the city and in which repository they are located.

The following Google Maps are intended to show the changes in the wards through time to the best of our knowledge. If you would like to download the KML file for a map, simply click on the “View Larger Map” underneath the image, and then click “KML” below the map name.

Links to the laws and ordinances which created these ward boundaries and changes are located under each map heading.
