Here are some maps of basic ares in Isengard, as well as a map of Isengard itself.
There are two versions of the Isengard world map, a higher resolution map (800x600) which is about 100k in size, and a smaller resolution map (640x480) which is about 70k in size. The Isengard world map was created by Justin Owens.
Justin is also working on making new maps of the main cities in Isengard. These maps are highly graphical. For less graphical maps of the cities (although without street names) visit the Isengard Grimoire. Maps of specific areas in Isengard can also be found at there all maps at the Grimoire were created by Kimiye Welch. You can find copies of some here as well. These maps are fairly specific and you may want to explore on your own before looking at them.
If you've created a map of Isengard or a specific area, email the webmaster and we will be happy to host it on this site.
