About
About Olbia Pontica — Southern Lower Town Harbour (Bug Liman South)
Southern lower town harbour below Olbia's acropolis on the Bug Liman, where the Milesian city's principal Black Sea harbour now lies 1–2 m submerged south of the terrace slope. Distinct from the northern mole sector in wave-6, this southern basin preserves a 140 m curved mole at –1.8 m, agora-adjacent ashlar quay 100 m at –1.5 m and 6th c. BCE apsidal house foundations at –1 m examined by 2015–2022 NASU underwater coring and drone LiDAR. Founded c. 647 BCE, Olbia was Borysthenes emporium for Scythian grain until c. 50 CE Getic sack; southern mole shielded southwesterlies and served deep-draught ships while north handled river barges. Agora quay bears Olbian dolphin coin votive scatter.
Why it mattersSouthern harbour proves dual Bug/Dnieper port system; agora quay and coin scatter date Olbian assemblies and Borysthenes grain tolls.
