The Stelvio Pass (Passo dello Stelvio ˈpasso dello ˈstɛlvjo, - ˈstelvjo or Giogo dello Stelvio ˈdʒoːɡo dello ˈstɛlvjo, - ˈstelvjo; Stilfser Joch ˈʃtɪlfsɐ ˈjɔx) is a mountain pass in northern Italy bordering Switzerland at an elevation of above sea level. It is the highest paved mountain pass in the Eastern Alps, and the second highest in the Alps, below France's Col de l'Iseran (). The pass is located in the Ortler Alps in Italy between Stilfs ("Stelvio" in Italian) in South Tyrol and Bormio in the province of Sondrio. It is about from Bolzano and 200 m from the Swiss border. The Umbrail Pass runs northwards from the Stelvio's western ramp, and the "Three Languages Peak" (Dreisprachenspitze) above the pass is so named because this is where the Italian, German, and Romansh language-speaking areas meet. The road connects the Valtellina with the Vinschgau valley and the town of Meran. Adjacent to the pass road there is a large summer skiing area. Nearby mountains include Thurwieserspitze, Piz Umbrail, Piz Cotschen, and to the east, the mighty Ortler. The original road was built in 1820–25 by the Austrian Empire to connect the former Austrian province of Lombardy with the rest of Austria, covering a climb of . The engineer and project manager was Carlo Donegani (1775–1845). Since then, the route has changed very little. Its seventy-five hairpin turns, 48 of them on the northern side numbered with stones, are a challenge to motorists. Stirling Moss went off the road here during a vintage car event in the 1990s, with an onboard video of his incident being shown on satellite TV. Before the end of World War I, it formed the border between the Austro-Hungarian Empire and the Italian Kingdom. The Swiss had an outpost and a hotel (which was destroyed) on the Dreisprachenspitze (literally, Three-Language-Peak). During World War I, fierce battles were fought in the ice and snow of the area, with gun fire even crossing the Swiss area at times. The three nations made an agreement not to fire over Swiss territory, which jutted out in between Austria (to the north) and Italy (to the south).
