OpenHistoricalMap goes beyond the present, mapping places throughout the world… throughout the ages.
No community is too small, no story too obscure to add to this map.
Everyone has something to contribute, including you!

Contribute
To contribute to OpenHistoricalMap, go to the main map, zoom in to a place of interest, and click the "Edit" button. If you are familiar with editing OpenStreetMap, the OpenHistoricalMap editing experience is very similar. See the tagging guidelines for information on a few changes we've made to accommodate the time dimension.
We also maintain several software projects to facilitate map contributions and data reuse. Please report any issues and send us your ideas on GitHub.
