Porta Asinaria
Monument Ancient Roman gate in Aurelian Walls, southeastern access
A surviving Roman gate in the walls of Rome, Porta Asinaria attracts walkers exploring the city’s ancient fortifications and nearby Late Antique and medieval sites.
Porta Asinaria is an ancient city gate in Rome, incorporated into the Aurelian Walls constructed in the late 3rd century AD. The gate survives as a combination of Roman walling with later medieval modifications.
The structure presents visible phases of construction from the imperial period through the Middle Ages, and it stands adjacent to modern streets in Rome’s southern sector. Although not a large tourist site, it is of interest to those tracing the city’s defensive architecture and urban development.
Erected with the Aurelian Walls in the late 3rd century AD, the gate has been altered and repaired in later centuries, particularly in the medieval period when many of Rome’s gates were fortified or adapted. It has continued to stand as part of the city’s historic fabric through modern times.
The gate is located on Rome’s southern perimeter within the historic city, near the Baths of Caracalla and the Lateran area, and is visible from nearby streets that follow the line of the ancient walls.
- Origins: Built as part of Rome's outer defensive circuit in the late 3rd century AD, the gate retains visible medieval alterations and later repairs.
