The Roman boundary marker at the Jaillet pass is one of Val d'Arly's rarest ancient remains. Together with the markers of the Petit Croisse Baulet and L'Avenaz, they offer the excuse for a themed walk open to good walkers (7 hrs walking).
The boundary marker of le Jaillet, found again in 1963, was built in 74 A.D. by the Romans in order to demarcate the territories of Ceutrons and Allobroges tribes. The word "FINES", that means "limit", is carved on it. Until the 18th century, it marked the border of mountain pastures between La Giettaz and neighbouring territories. This marker, just like others, has been thrown down the slope or hidden in order to blur the border, because of conflicts and trials about the boundaries of pastures.
