About
About Lysimachia — Northern Harbour at Hebros Delta North (Thrace North)
Northern delta harbour of Lysimacheia on the Hebros (Evros/Maritsa) northern distributary in eastern Thrace polder, where Lysimachus's 309 BCE Thracian capital harbour now lies 2–4 m under deltaic silts north of the Hexamili ridge. 8 m and Lysimachus palace causeway 60 m at –1 m cored by 2018 Evros Delta geoarchaeology. Founded 309 BCE by Lysimachus, capital of Thrace until 281 BCE Seleucid sack; northern harbour handled Hebros timber via Strymon road while south handled Aegean sea mouth.
Causeway links palace acropolis.
Why it mattersNorth harbour proves bipartite Lysimacheia delta harbour (north distributary vs south sea mouth); quay dates Lysimachus urbanism and Hebros delta engineering.
