Maps
Here's a useful resource for your bookmarks. The Perry-Castañeda Library Map Collection at the University of Texas has a great page of links to maps from historical atlases. They also have images from some of the maps in their own collection.
If you're trying to work out where the borders of the Duchy of Burgundy ran at the end of the fourteenth century, or you just want an example of a manor, a city or an empire on which to base an imaginary place, there's probably a map in there you can use.
ETA:There are more map links at The Internet Medieval Sourcebook.
For links to images of maps that actually date from the Middle Ages, take a look at the following pages hosted by Henry Davis consulting. Early Medieval Maps covers the period from 400 to 1300 and Late Medieval Maps covers 1300-1500. Keep in mind that medieval maps did not serve all the same purposes than modern ones do. They were symbolic representations of the world, rather than navigational aids. Occasionally a medieval illustrator would produce a diagram to aid travellers, but these tended to take the form of itineraries with straight lines leading from one city to the next, like Matthew Paris' thirteenth-century diagram of the route from Bar-Sur-Seine to Troyes below.
