Switzerland may look small on a map—its total area is smaller than the state of West Virginia—yet within its borders it has a dozen UNESCO World Heritage sites, three of them natural wonders and the other nine cultural ones. The sites embody the diversity of the country, its peoples, and its landscapes. The Swiss Alps Jungfrau-Aletsch site features a remarkable diversity of ecosystems, in the shadow of iconic peaks where you’ll also find Eurasia’s largest glacier. At Monte San Giorgio, you’ll learn that while today images of snowy peaks may come to mind when you think of Switzerland, 240 million years ago, this site was the location of a vast tropical lagoon (numerous fossils from that era can be found here). Man-made wonders range from prehistoric pile dwellings to the medieval cityscape of Bern’s Old City and modernist masterpieces by one of the 20th century’s most celebrated architects, Le Corbusier.
