The Eiger is a mountain in the Swiss Alps. It is the easternmost peak of a rige-crest that extends to the Mönch (4,107 m) and across the Jungfraujoch to the Jungfrau (4,158 m). The peak is mentioned in records dating back to the 13th century but there is no clear indication of how exactly the peak gained its name. The three mountains of the ridge are sometimes referred to as the Virgin (German: Jungfrau, lit. "Young Woman" - roughly translates to "Virgin" or "Maiden"), the Monk (Mönch) and the Ogre (Eiger). The name has been linked to the Greek term akros, meaning "sharp" or "pointed", but more commonly to the German eigen, meaning "characteristic".
