Porta Praetoria, Roman city gate in Aosta, Italy.
The Porta Praetoria features three distinct openings: a central passage for vehicles and two lateral entries designed for pedestrian access through the fortification walls.
The gate was constructed in 25 BCE as part of Augusta Praetoria's defenses, following the Roman victory over the Salassian tribes by commander Terenzio Varrone.
During the medieval period, a Trinity Chapel was built on top of the gate's patrol walkway, influencing its name and function for several centuries.
Visitors can explore the gate structure and surrounding Roman walls on foot throughout the year, with guided tours offering detailed information about the architectural elements.
The eastern facade retains original marble slabs while the interior construction reveals substantial puddingstone blocks, demonstrating Roman architectural techniques.
