About Kourion Harbour – Submerged Anchorage at Episkopi Bay
Kourion's harbour beneath Episkopi Bay cliffs, 1.3 km southwest of the acropolis, preserves submerged Roman quay blocks at –2 m and rock-cut bollards drowned by the 365 CE earthquake that toppled Kourion. Leonard–Demesticha diving mapped 80 m ashlar quay with mooring holes at –2 m, and offshore anchorage with Dressel 20 and Late Roman 1 amphora piles at –8 to –12 m. Harbour basin cores show harbour mud with 2nd c. BCE–4th c. CE ceramics sealed under earthquake-tsunami sand. The acropolis cliff above collapsed, sealing harbour warehouses now waterlogged. Sea-level curve for Limassol anchors to Kourion quay subsidence of ~1.5 m since Roman peak.
Why it mattersBest Cypriot quay subsidence marker; harbour tsunami sand horizon anchors 365 CE earthquake sea-level and trade break.
