Porta Metronia, Ancient city gate in Rome, Italy
Porta Metronia is a passage through the Aurelian Walls, one of Rome's major defensive systems from ancient times. The original gateway lies partially underground today and reveals the solid stone construction typical of such fortifications.
Emperor Aurelian built this structure around 271 AD as part of a massive wall system designed to protect Rome from invaders. The gate initially served as a small hidden exit from the city.
The gate structure includes two commemorative plaques from 1157 and 1579, documenting restoration works by the Senate of Rome and Pope Gregorius XIII.
The gate is located along Via dell'Amba Aradam in southern Rome, close to the Basilica of Saint John In Lateran. Visitors should note that the original passage area lies partly below the current ground level.
The gate was once connected to a water channel called the marrana, which powered fourteen water mills in the area. This water source created a marshy zone around the gate known as Il Pantano.
