Most of Europe is now covered by the Eupedia Travel Guide (EU + Switzerland, Norway, Iceland, but without Cyprus and Malta). The map below ranks regions of Europe from the most to the least interesting for sightseeing based on the density and rating of cities, towns, castles ans well as naturals parks and other attractions. The map division is based on the EU's NUTS2 regions, although a few regions were merged to restore historical regions or present states (e.g. Bavaria and Lower Saxony). As NUTS2 regions were created taking populations into account, regions with high population densities like England and the Benelux have smaller land areas. It's actually suitable for the purpose of this map, as more densely populated regions tend to have a greater density of attractions as well.
