)[1] Groups continued to live in or seasonally visit the cave throughout the Mesolithic and Neolithic eras, with occasional short episodes of apparent abandonment.

[2] Last occupied around 3,000 BC (Final Neolithic), Franchthi was used as a shelter for around 35,000 years and is one of the most thoroughly studied sites from the stone age in Southeast Europe.

[9] Obsidian from the island of Melos appears at Franchthi as early as 13,000 BC, offering the earliest evidence of seafaring and navigational skills by anatomically modern humans in Greece.

[17] There is a notable stretch spanning several hundred years (circa 7,900 – 7,500 BC) when tuna became a major part of the diet at Franchthi Cave,[18] implying deep sea fishing.

[26] During the Neolithic, the main occupancy of the cave shifted to an area outside the entrance, called the Paralia (the seaside),[27] where terracing walls for growing crops were built.

The Franchthi area of Kiladha Bay is considered a strong candidate for having a submerged Neolithic village, and in 2012 a search was launched for any underwater evidence of such a site.

[31][32] In 2014 the Terra Submersa team, led by Julien Beck, was waiting for permission to conduct their survey of the Franchthi area of Kiladha Bay.

The visible remains of Lambayanna are dated to the Early Helladic II era (c. 2650 – c. 2200 BC), making it a contemporary of the House of the Tiles at Lerna, the building of the Great Pyramids, and both the Cycladic and Minoan cultures of the nearby Aegean islands.

[33][34][35][36] The Bay of Kiladha Project continues to study the find at Lambayanna, while maintaining its search for a prehistoric settlement directly off the shore of Franchthi Cave.
