The Matterhorn, Monte Cervino (Italian) or Mont Cervin (French), is one of the highest peaks in the Alps. The mountain overlooks the town of Zermatt in the canton of Valais to the north-east and Breuil-Cervinia in the Aosta Valley to the south. The Matterhorn has become an iconic emblem of the Swiss Alps and the Alps in general. Since the end of the 19th century, when railways were built, it attracted more and more visitors and climbers. Each summer a large number of mountaineers try to climb the Matterhorn via the northeast Hörnli ridge, the most popular route to the summit.
