Many travelers recognize the significance of the designation conferred by the United Nations Educational, Scientific and Cultural Organization. UNESCO World Heritage sites are comprised of some 878 properties worldwide which form “part of the cultural and natural heritage that the World Heritage Committee considers as having outstanding universal value.” By meeting strict criteria pertaining to natural or cultural significance, some of Europe’s most obvious places are included on the list. It comes as no surprise, for example, that Cologne’s cathedral, southern Italy’s Pompeii, Athens’ Acropolis and the west Norwegian fjord landscape all make the cut.
