About
About Olbia Pontica — Parutyne Northern Mole on Bug Estuary (Borysthenes)
Northern mole of Olbia Pontica on the Bug (Hypanis) estuary, where Milesian Olbia's lower town harbour now lies 1–3 m submerged at Parutyne. Distinct from the southern lower town second phase already in database, this northern harbour preserves 120 m ashlar-concrete mole at –2 m, riverine quay with timber pilings and 5th c. BCE Stoa foundation drowned at –1.5 m mapped 2016 NASU-Olbia underwater coring. Founded by Milesians c. 647 BCE, Olbia was Borysthenes emporium for Scythian grain until Roman sack 270 CE. Northern mole shielded northeasters up Bug Liman and served river barges.
Why it mattersNorthern mole proves dual Bug/Dnieper harbour system; river quay timber dates calibrate Olbia-Scythian grain trade and Liman relative sea-level.
