The Aqua Alexandrina is an ancient Roman aqueduct ( aqueduct ) to supply the city of Rome . It is the last aqueduct to be built in ancient Rome.
history
The Aqua Alexandrina was built under the rule of the Emperor Severus Alexander in AD 226 and named after its builder. Severus Alexander, also in the year 226 AD, had the thermal baths of Nero on the Field of Mars restored and rebuilt as well as significantly enlarged. They were renamed after him as the baths of Alexander . For these enlarged thermal baths, Alexander needed a new water supply.
A total of three restorations were verified. The aqueduct was last repaired during the reign of Pope Hadrian I.
The sources of the Aqua Alexandrina are now used by the Acqua Felice . An aqueduct that Pope Sixtus V had built in 1586. However, it reaches Rome on a different route and ends in the Well of Moses .
In Rome's Tor Pignattara was Parco dell'Acquedotto Alessandrino set up in the still part of the aqueduct can be seen.
Water flow
The source of the Aqua Alexandrina was in the Pantano Borghese , a swamp near the ancient city of Gabii on the Via Praenestina east of Rome. Today the area belongs to the municipality of Monte Compatri .
From there, the approximately 22.5 km long aqueduct initially ran underground for a section of 6.4 km, and then covered the rest of the route as an aqueduct on an arch construction and a series of gentle valleys, intersected by the tributaries of the Anio (later Aniene ) to cross.
The Aqua Alexandrina led near the Porta Maggiore over an aqueduct made of brick arches along the Via Praenestina and the Via Labicana and ended on Campus Martius at the thermal baths of Alexander . The thermal baths were located between the Pantheon and today's Piazza Navona .
Depending on the season, the water flow was 120,000 to 320,000 cubic meters per day.
