An infrastructure that supplied water
Built between the second and third centuries AD, the aqueduct carried water from the springs at Cabu Abbas to Olbia’s baths along a 3.5-kilometre route. It was more than a striking arch: the system connected a water source with public facilities in the Roman city. That purpose helps you read the remains as part of an urban infrastructure.
The municipal page calls it the best-preserved Roman aqueduct in Sardinia; that is the source’s description. Its route crossed a landscape later transformed, and the visible remains are sections of the system rather than one continuous walk open along all 3.5 kilometres. Plan around a specific site instead of expecting a single linear trail.
The Sa Rughittula section
At Sa Rughittula on Via Mincio, the listing describes a section over one hundred metres long with two intact arches and a piscina limaria. This settling basin helped separate impurities before water continued through the system. The arches show the raised channel; the basin reveals a less dramatic but essential part of its operation.
The page also notes a concrete cistern opposite, perhaps associated with a villa or estate. Keep the “perhaps”: the source does not confirm its purpose. When looking at the site, distinguish the raised channel, settling basin and cistern rather than assigning the latter a function beyond what is documented.
Other remains within the city
The aqueduct is not limited to Sa Rughittula’s arches. The municipality lists further remains on Via Nanni and Via Canova; on Via Nanni, a section crosses a Punic residential and artisan block. Excavations there found nine bases for pillars that once supported Roman arches and the water channel.
These are separate fragments within modern streets, not necessarily a connected archaeological walking route. Choose one stop at a time, follow municipal directions and keep building entrances and businesses clear. Via Nanni is especially useful for seeing how Roman infrastructure was laid across an earlier neighbourhood.
Getting to Sa Rughittula
For the main section, Hello Olbia directs visitors to Via Mincio: from the Via dei Lidi roundabout, take the third exit, turn left and follow the paved road for about one kilometre to the site parking. Check that directions and access remain current, then follow signs on arrival.
The municipal listing says access is free at any time and mentions information panels, but local conditions or works can change. Do not climb on the remains or cross barriers; view the arches from accessible points. If you also want to see Via Nanni or Via Canova, plan them as separate stops rather than treating them as one continuous trail.
