About
About Franchthi Cave — Koilada, Argolid
Franchthi Cave (Upper Paleolithic to Final Neolithic c.38,000–3000 BCE) is a vast 30-m wide limestone cavity on the Koilada Bay cliff 10 m above the now-submerged plain, containing a 5-m stratified sequence from Upper Paleolithic blades to Mesolithic microliths and earliest Aegean Neolithic pottery and emmer 6500 BCE. Excavated by T. W. Jacobsen (Indiana) 1967–79, its 25,000 obsidian pieces trace Melos sourcing from 11th millennium and the controversial early seafaring, while molluscan isotopic study tracks Holocene transgression.
Why it mattersLongest Aegean sequence; earliest Greek agriculture and seafaring evidence.
