Olba is revealed through an ancient water supply system
Olba is an ancient city in the Silifke district of Mersin, where history is evident not only in its theater and necropolis. One of the most striking monuments here is a two-tiered Roman aqueduct. It serves as a reminder that the settlement's survival depended not only on its hillside location but also on its ability to transport water from afar.
For those exploring Mersin beyond the coast, Olba offers a glimpse into the region's other landscapes: inland valleys, ancient settlements, and engineering structures connected to the daily lives of ancient residents.
A city between the Hellenistic, Roman and early Christian periods
The official map of the Ministry of Culture and Tourism describes Olba as an important commercial and religious center during the Hellenistic period. During the early Christian era, Olba and neighboring Diocesarea—today's Uzungaburch—were separate episcopal centers.
How water traveled from the spring to the city fountain
According to the official description, water from the Lamas River was channeled through canals, tunnels, and aqueducts to the city fountain. The fountain was built under Septimius Severus, who reigned from 193 to 211 CE.
The aqueduct over the necropolis valley was two-tiered, 150 meters long and 25 meters high. A source dates it to 199 CE, during the reign of Septimius Severus, and reports repairs in 566 under the Byzantine Emperor Justin II. An inscription on the structure reads "City of the inhabitants of Olba.".
Fountain, theater, and necropolis: what remains
In addition to the fountain and aqueduct, Olba contains the remains of residential buildings, a theater, and a necropolis. In the theater, individual rows of seats and part of the stage are visible; in the necropolis, rock-cut tombs and sarcophagi. Religious monuments include the remains of churches and a monastery in the valley to the east of the acropolis.
How to plan a trip from Mersin
Olba is located four kilometers east of Uzungaburch. The official map indicates access by private or rental car.
- Check the road to Olba itself; if you're traveling without a car, check the current public transportation connections in advance.
- Before leaving, check the visiting hours and restrictions. The card does not include current schedules, prices, or travel times; access for your selected date must be checked separately.
- When on site, stick to designated paths and do not climb on fragile structures or masonry fragments.
