The Olba Aqueduct is a striking remnant of Roman engineering in southern Turkey, commissioned by Emperor Septimius Severus in 199 AD. Spanning a valley near the ancient city of Olba, this double-tiered structure once carried water from the Limonlu River to the settlement. Though mostly in ruins today, a 150-meter section still stands, reaching heights of 25 meters—a testament to its original grandeur. Visitors can observe the remaining arches and nearby Byzantine-era observation towers, evidence of repairs made under Emperor Justinian I in the 6th century.
Located just 4 km east of Uzuncaburç (ancient Diokaesareia), the aqueduct offers a glimpse into the region's Roman and Byzantine past. Wear sturdy shoes for exploring the uneven terrain, and visit in early morning or late afternoon for softer light and cooler temperatures. Combine your visit with nearby Olba ruins for a fuller historical experience.
