2,500 Historic Maps of Germany

Virtuelles Kartenforum 2.0 is a collection of over 2,500 geo-referenced historical German maps.

Using the Virtuelles Kartenforum portal you can search for an historical map by name. You can also search by date range and by location. To search by location you can pan and zoom the map and all the available historical maps within the current map bounds will be listed in the map sidebar.

Select an historic map from the results and you can view it as an overlay on an OpenStreetMap. You can overlay as many historical maps over the modern map as you like and you can control the opacity of each map that you have added.
