Franchthi cave or Frankhthi cave (Greek: Σπήλαιον Φράγχθη) is a cave overlooking the Argolic Gulf opposite the village of Koilada in southeastern Argolis, Greece. The cave was occupied from the Upper Paleolithic circa 38,000 BCE (and possibly earlier) through the Mesolithic and Neolithic periods, with occasional short episodes of apparent abandonment. Last occupied around 3,000 BCE (Final Neolithic), it is one of the very few settlements in the world that shows nearly continuous human occupation for such an extended period of time, and is one of the most thoroughly studied sites from the stone age in southeastern Europe.
