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.
The city gate was built during Roman rule in the 1st century AD. It consists of massive stone walls and arches, characteristic of the Roman architecture of that time. The Porta Praetoria was constructed to serve both defensive and ceremonial purposes.
