In 2014 PlanetSolar was a part of the Terra Submersa program of the University of Geneva, which joined an underwater archaeological survey in Greece. The target was an area of Kiladha Bay just off the coast of Franchthi Cave, a site known to have been occupied by prehistoric humans for 35,000 years, and where it was believed there could be a submerged Neolithic village under waters that had risen significantly after the last ice age. While waiting for government permission to conduct their survey off the cave shore, PlanetSolar’s team practiced diving several hundred yards north at Lambayanna Beach and discovered very old pottery and strange formations on the seafloor. Returning with PlanetSolar in 2015 they discovered the underwater remains of a 3-acre (1. 2 ha) Early Bronze Age village that has been given the eponymous name Lambayanna.
