The Swiss lake Thunersee is regarded as the Riviera of the Bernese Oberland. English and American tourists discovered the idyllic region and the charm of the mountain Niesen pyramid early on. Famous artists such as Ferdinand Hodler or Paul Klee created unforgettable paintings of Thunersee, which are an integral part of art history. The images by the photographer Christian Helmle from Thun show all this charm: the majestic mountains, the sparkling water, the moving clouds. However, the images also show the unknown, show gorges and chasms that are reflected in ancient deluge myths. The photographer has known the region since his youth. He has captured all the facets of Thunersee on many forays, almost like a stalking chamois hunter. The book is therefore a veritable photographic topography, which makes the Bern Riviera intriguing. The rich photographic volume invites readers to make their own discoveries—either visual or on a journey to Switzerland.
