Great St. Bernard — The Peddlers' Register
You are Pierre Chanel, a 19th-century Augustinian monk at the Grand-Saint-Bernard Hospice, tasked with documenting the confidential tales of peddlers and pilgrims traversing the Grand
Cross the Alps at the Grand-Saint-Bernard Pass, where Roman legions and Via Francigena pilgrims have left their mark for millennia.
The story that haunts this land
Your journey begins in front of the Grand-Saint-Bernard Hospice, a building founded around 1050 by Augustinian monks under the impetus of Saint Bernard of Menthon. Located at an altitude of 2473 m, this hospice is a landmark of Swiss Alpine heritage, welcoming pilgrims and travelers since the 11th century. Rebuilt in 1824 after the 1757 fire, it consists of two historic buildings, the old and the new, which have seen countless souls pass through on the historic Via Francigena route. It is here, in the heart of col-du-grand-saint-bernard, that you will begin to decipher the first clues of your GPS treasure hunt.
Continue towards the Statue of Saint Bernard of Menthon, erected in 1896 at the entrance of the Hospice to honor its founder, the patron saint of mountaineers. The Grand-Saint-Bernard Pass, at 2473 m, is the 3rd highest road pass in Switzerland, a strategic point open from May to October. It was paved by the Romans in the 1st century with bridges and trenches, long before the Lombards crossed it in 1476. Your visit to col-du-grand-saint-bernard will reveal how this Alpine road pass remained a major north-south route in the Alps, constantly reshaped by history.
Beneath your feet, the remains of the Temple of Jupiter recall a Roman presence from the 1st century BC. These ruins of the Forum Clodii, discovered beneath the Hospice, attest to an ancient sanctuary on the Roman road crossing the pass. Valais is full of these silent testimonies. As you walk along the Grand-Saint-Bernard Lake, a small Alpine lake at ~2460 m altitude, you will understand its role as a natural landmark integrated into the historic trails. This thematic circuit in col-du-grand-saint-bernard invites you to an interactive visit of the layers of history.
Your itinerary then leads you in the footsteps of the Via Francigena, this ancient pilgrimage route that has crossed the pass since antiquity, connecting Canterbury to Rome. The monks of the Hospice developed the Saint Bernard dog breed in the 18th century for avalanche search and rescue, a living tradition you will discover at the Museum and Kennel of the Saint Bernard Dogs. This museum exhibits historical objects and traces the history of rescue dogs since their first mention in 1707, a touching aspect of Valais heritage.
Concluding your journey in front of the Grand-Saint-Bernard Hospice, you will have explored not only one of the highest Alpine hospices, but also a millennia-old crossroads where Romans, pilgrims, and rescuers have met. Your treasure hunt in col-du-grand-saint-bernard will have allowed you to discover precise anecdotes about the founding of the Hospice, the importance of the pass as a strategic passage, and the history of rescue dogs. This interactive circuit in Valais offers you a unique perspective on Alpine heritage and the history of this emblematic place.
