 Argentarola cave lies close to Argentario promontory.The high quality speleothems that have been collected from this cave have allowed scientists to study the 215,000 year history of sea-level oscillations in this region.The promontory, probably already inhabited by the Etruscans, was a personal property of the Domitii Ahenobarbi family, who obtained it in return for the money they lent to the Roman Republic in the Punic Wars.
