Pont de Pierre, Roman stone bridge in Aosta, Italy
Pont de Pierre is a Roman stone bridge in Aosta spanning 17 meters with a width of about 6 meters. It features a flat arch vault constructed from rough stone and Roman mortar.
The bridge was built in the second half of Emperor Augustus's reign, between 30 BC and 14 AD. It served as part of a key military and trade route system connecting to Alpine passes.
The bridge shows the craftsmanship of Roman builders through its flat arch design and large stone wedges. Visitors walking across it can observe the techniques used two thousand years ago.
The bridge is located about 300 meters from the Arch of Augustus and is easy to reach when exploring the old town center. It is worth visiting it together with other Roman remains nearby to get a fuller picture of the ancient city.
The river that once flowed under the bridge changed its course over centuries, leaving the structure standing dry today. This unusual detail makes it a rare example of a Roman bridge that visitors can walk across without water flowing beneath.
