About
About Astypalaia Harbour – Submerged Quays of the Dodecanese Port
Astypalaia, the butterfly island bridging Cyclades and Dodecanese, preserves submerged Hellenistic quays at −1 m to −3 m in Chora harbour and at Kaminakia Bay (36.5171N 26.3053E). The Chora harbour mole (80 m) and quay blocks are visible snorkelling off the Venetian Querini castle hill; Kaminakia Bay revealed submerged rock-cut slipways. The island was the refuge of the Astypalaean Venetian duchy (1207–1522). Quays exported sponges and Tyrian purple from nearby islets. Survey by the Ephorate of Underwater Antiquities (Dodecanese).
Why it mattersOnly Dodecanese harbour bridging Cycladic and Carian networks; shows Venetian reuse of Hellenistic mole.
