The Matterhorn is a mountain of the Alps , straddling the main watershed and border between Switzerland and Italy. It is a large, near-symmetric pyramidal peak in the extended Monte Rosa area of the Pennine Alps, whose summit is 4,478 metres (14,692 ft) above sea level, making it one of the highest summits in the Alps and Europe. Sometimes referred to as the "Mountain of Mountains" (German: Berg der Berge), it has become an indelible emblem of the Alps and stands as the most photographed mountain in the world. The Matterhorn has four faces, each roughly oriented toward one of the four cardinal points. Three of these (north, east, and west) are on the Swiss side of the border and watershed, while the south face lies on the Italian side. These four steep faces, rising above the surrounding glaciers, are separated by the Hörnli, Furggen, Zmutt, and Leone (Lion) ridges.
