The Jungfraujoch (German: lit. "maiden saddle") is a saddle connecting two major 4000ers of the Bernese Alps: the Jungfrau and the Mönch. It lies at an elevation of 3,463 metres (11,362 ft) above sea level and is directly overlooked by the rocky prominence of the Sphinx. The Jungfraujoch is a glacier saddle, on the upper snows of the Aletsch Glacier, and part of the Jungfrau-Aletsch area. 

Since 1912, the Jungfraujoch has been accessible to tourists by the Jungfrau line, a railway from Interlaken and Kleine Scheidegg, running partly underground through a tunnel through the Eiger and Mönch. The Jungfraujoch railway station, at an elevation of 3,454 metres (11,332 ft) is the highest in Europe. It lies east of the saddle, below the Sphinx station, and is connected to the Top of Europe building, which includes several panoramic restaurants, shops, exhibitions, and a post office.
