Aqua Alexandrina Archaeological Site

Address: Parts of Aqua Alexandrina’s route are in the eastern/southeastern districts of Rome; no single modern visitor center

The Aqua Alexandrina (Acqua Alessandrina) is a Roman aqueduct named after Emperor Alexander Severus that supplied water to parts of Rome in the third century AD.

Surviving elements comprise sections of channeling, masonry remains and later-era reutilisations incorporated into the urban fabric; some traces are visible in northeast Rome where the supply entered the city. Remnants are mostly archaeological features rather than a continuous above-ground structure.

Constructed under Alexander Severus in the early third century AD to augment Rome’s water supply, the aqueduct later fell into disuse and parts were repurposed in the medieval and modern periods. Its route and remains have been documented by archaeological study.

Remains are located within the city of Rome in the Lazio region, with visible traces and later fountains and conduits in the northeastern sectors of the ancient city.

• Origin: Named for the Severan emperor who commissioned it, the aqueduct supplied water to parts of Rome in the later Roman imperial period.

Fragments of the aqueduct run through Rome’s southeastern districts. Access requires local maps and some walking; many parts are visible from public roads and parks. Combine with other archaeological sites in the area for a longer day of exploration.

• Look for the aqueduct's surviving masonry along the eastern side of Rome; many fragments are best seen with a good map and a knowledgeable guide.
• Combine a visit with other nearby aqueduct remains and the Baths of Caracalla for a fuller sense of Rome's water system.
• Bring a focused lens or binoculars to see the engineering details on distant arches.
