Porta Pretoria (Aosta)

Highlight • Historical Site

The Porta Praetoria was one of the main gates of the Roman city of Augusta Praetoria Salassorum, as Aosta was called in ancient Rome. It served as the main access to the city from the side of the Roman road that crossed the Aosta Valley. The location of the gate is strategic as it allowed the connection between the Roman Forum and the Roman Theater.

Allein Village Center

Highlight • Settlement

Allein is a small jewel perched on the slopes of Mont Saron. Allein's origins are lost in the mists of time. It is hypothesized that its name derives from the Latin "Allius", or from the presence of the Alans, a Sarmatian tribe that settled here in the 5th century AD. Other scholars, however, trace it back to medieval Germanic contamination. The Roman era has left its mark on the territory: in 1856 several silver coins dating back to the Republican era were found, today kept in the Académie Saint-Anselme museum in Aosta. In the Middle Ages, Allein belonged to the Lordship of Gignod, then passing under the dominion of the Savoy in the 16th century.

Col du Grand Saint-Bernard

Highlight • Mountain Pass

This climb is something incredible: it doesn't have difficult gradients but it's long, very long, endless. You reach a point where you almost hate it: you've been cycling for well over an hour and still can't see the summit, you're running out of energy and the wind keeps whipping your face, you'd like to throw your bike away and say "Enough! I'm stopping here"... but it's only for a moment, because you're the one who chose to face it and you knew perfectly well what you were getting into; you set off again with more grit than before and tackle those last few km of road with all your remaining strength.
And then you enter the tunnel, there you start to realize you've made it, you come out, follow the road that turns slightly to the left and, as if in a dream, the lake appears.
You reach the top and think about how many people throughout the centuries have traveled this road: Salassi, Romans, monks, migrants, Napoleonic soldiers... you realize you are in a place where History is dense and nature is stunning, and there you can only love this hill
