An extensive complex of quarries for surface and underground mining of the famous Parian marble, the so-called Paria Lithos, was developed in Marathi in antiquity (mainly from the 7th century BC onwards). Today it is known that the quarries covered a wide area that included, in addition to the most famous galleries of the Nymphs and Pan, the underground mining in Spilies, as well as the surface excavation on the hill of Lakki and at Thapsana.
