Ancient Rome on Google Maps

The Pelagios Project has released Roman Empire map tiles that can be used with the Google Maps API. They have released a demo map, Digital Map of the Roman Empire, which shows how the map can be used with the Google Maps API.

The demo is just a basic map which replaces the Google Map tiles with the Roman Empire map tiles. If you want to search the map for ancient world place names then you should check out the Pleiades website. Pleiades is a great resource for anyone interested in the history and geography of the ancient world. The site is a community based and open-sourced gazette of ancient places.

If you search Pleiades for a Roman place name you can view the location on a map. On the displayed map you need to select the 'Imperium' map layer to view the Roman Empire map tiles.
