    Dug more than 500 years ago between France and Italy, the "Pertuis du Viso" today renamed "La Traversette" is the first tunnel in Europe. It had an extraordinary history before sinking into indifference.
    This tunnel opened in 1480 at an altitude of 2850 m and is now the oldest in the Alps. It allowed to pass from the Dauphiné to another country, the Marquisate of Saluce! It was an underground link between the basins of the Guil and the Po.
    This tunnel was essentially dug to ensure the security of the salt supply for the population and the livestock of the transalpine valleys.
    Over the centuries this passage has become one of the most valuable pieces of historical heritage of the Alps and Europe.
    Today, the Traversette Tunnel is still under threat from erosion and landslides, but hikers can still use it in summer.
