About
About Caulonia – Achaean Harbour at Monasterace
Caulonia, Achaean colony (700 BCE) at Monasterace Marina, anchored a small harbour now 1–2 m submerged along the Punta Stilo promontory. Iannelli-Tréziny excavations uncovered Doric temple terrace, city walls and offshore ashlar blocks mapped as harbour mole at –1.5 m, 80 m offshore. The harbour's submerged quay aligns with Stilaro river mouth now diverted; cores show harbour mud with 6th–3rd c. BCE Greek pottery sealed under tsunami sand of c. 400 CE. The mole's header-stretcher blocks match temple ashlar, indicating contemporaneous 5th c. BCE engineering. Harbour was abandoned after Bruttian wars and coastal progradation.
Why it mattersBest-preserved Achaean harbour in Calabria; mole ashlar links to Doric temple workshop and anchors Magna Graecia harbour technology.
