About
About Lysimachia — Submerged Harbour at Hebros Delta (Thrace) — v2
Harbour of Lysimachia, Lysimachus's 309 BCE capital at Hebros delta isthmus, now 1–2 m waterlogged in Lake Kaminia salt lagoon north of Saros Gulf. Distinct from other Hebros sites, Lysimachia preserves 100 m ashlar quay at –1.8 m, agora stoa 80 m at –1.2 m and city wall 500 m at –1 m mapped 2015 Thrace harbour coring. Lysimachus founded to control Thracian Chersonese grain, but Hebros avulsion and Saros siltation silted harbour by 200 BCE. Lake Kaminia cores show 309 BCE foundation horizon over Thracian salt pan. Harbour handled Black Sea via Hellespont.
Why it mattersLysimachia harbour anchors Diadoch Thrace urbanism and Hebros delta avulsion chronology; Kaminia salt cores calibrate Thracian Chersonese grain route siltation.
