Archaeologists have discovered an ancient Greek sanctuary in the Pertosa-Auletta Cave in southern Italy, confirming its historical significance as a gathering place for a Hellenistic cult during the 4th to 1st centuries BCE. The cave revealed a sacred area along its underground waterway, with artifacts suggesting ritual practices and religious activities during the Hellenistic period. The excavation also revealed a larger and more complex wooden village within the cave, which is considered unique in Europe. Researchers collected wood samples to determine the age and preservation of the structures.
