The Roman road at Donnas
A stretch of the Roman road to Gaul cut into the living rock, with an arch carved out of the stone and a milestone.
The story
To build the road linking the Po plain to Gaul, Roman engineers cut into the mountain for about two hundred metres, leaving a natural arch and a column marking thirty-six miles from Aosta. The ruts of cart wheels are still visible in the paving. Nearby, at Pont-Saint-Martin, a single-arch Roman bridge has spanned the Lys stream for over two thousand years.
Why go
Walk on the same stone worn down by Roman carts, among the Donnas vineyards.
