Here are some splendid medieval maps.
While they might sometimes be inaccurate, and even downright silly, nobody can possibly say that all of them are simple T maps, with Jerusalem at the center. Some of them, like the map of Scandinavia, are verging on the accurate.
Others of these maps depict cities and such. That’s neat!
It could be said that the medieval map sometimes comes out more as works of art than as reference material for travellers. And heck… that might even be a good thing…
