The Simplon Pass is located at 2008 m. (or 6589 ft.). It connects the Pennine Alps and the Lepontine Alps in Switzerland. It connects Brig in the canton of Valais with Domodossola in Piedmont (Italy).
The pass acquired international significance during the Napoleonic occupation. Between 1801 and 1805 a road was constructed at the direction of the emperor in order to transport artillery pieces through the pass between the Rhône valley and Italy. Since then, the pass has been usable by post carriages, replaced early in the twentieth century by post buses.
The Simplon Tunnel was built beneath the vicinity of the pass in the early 20th century to carry rail traffic between the two countries.
