About
About Ephesus Harbour – Silted Kaystros Harbour
Ephesus harbour on the Kaystros (Küçük Menderes), once a 600×300 m imperial basin 3 km from the city, now 5 km inland silted 5 m above sea under apple orchards. Stock–Brückner cores (2003–2020) traced Hellenistic and Roman quay walls buried 4 m under alluvium at 37.95°N 27.32°E, and Hellenistic mole stump 80 m at +2 m. Harbour was dredged repeatedly under Lysimachus and Augustus; Delile 2021 dated final closure to 6th c. CE when Kaystros progradation sealed basin. Canal harbour (Artemision harbour) 2 km long linked city to sea. Silted basin is type-site for Kaystros delta progradation 3000-year record.
Why it mattersType-site for Cayster delta; quay and canal stratigraphy anchor 3000-year harbour silt chronology and Roman dredging tech.
