I was hunting around in Google Images for some tourist maps and came across this great website... Mappery (CLICK for their Italy maps listing). The site is dedicated to maps and lovers of maps. Contributors from all over the world scan and upload their maps. It's obvious that some are direct scans of travel worn (and wrinkled) maps direct from people's own voyages. All sorts of maps are on the site--tourist, hiking, topographical, historical, even a fantastic biking map of Rome and the surrounding countryside. Each map can be zoomed in on and panned, with most in very high resolution, so details are very clear. I was amazed at the large selection for Italy.
This is a great addition to your travel toolbox when planning your own Voyage to Italy.
