The massive composition of the Eiger, Mönch, and Jungfrau constitutes an emblematic sight of the Swiss Alps and is visible from many places on the Swiss Plateau and the Jura Mountains in the northwest. The higher Finsteraarhorn () and Aletschhorn (), which are located about to the south, are generally less visible and situated in the middle of glaciers in less accessible areas. As opposed to the north side, the south and east sides of the range consist of large valley glaciers extending for up to , the largest (beyond the Eiger drainage basin) being those of Grand Aletsch, Fiesch, and Aar Glaciers, and is thus uninhabited. The whole area, the Jungfrau-Aletsch protected area, comprising the highest summits and largest glaciers of the Bernese Alps, was inscribed as a UNESCO World Heritage Site in 2001.
