Maybe a bit late now, as the mapping brief's deadline passed ages ago, but the University of Belfast have created an interactive version of a map from the 14th century. Talk about old contrasted with new - some of the tools resemble those on Google Maps, produced some 600 years later! It's also interesting to see what the country looked like all those years ago, even if the cartography didn't prove to be wholly accurate.
