Often considered a natural rampart, the Alps are however not impassable. Through the presence of the Petit-Saint-Bernard, Bonhomme and Iseran passes, the Haute-Tarentaise valley has brought together important places of passage since prehistory. Since Antiquity, the Petit-Saint-Bernard pass has been a link between local Alpine populations. During the Roman conquest, Emperor Augustus completed the construction of the Roman road. Troops, sovereigns, pilgrims, merchants, bankers and peddlers cross paths on the roads. At the end of the Middle Ages, the County of Savoie controlled five crucial passes, including the Petit and Grand Saint-Bernard.
