The old Mines in Megalo Livadi Serifos: The history of Serifos is linked from the ancient times to the mines that exist on the island and which flourished and gave prosperity to the islanders. In the antiquity, slaves used to work in these mines, until they temporarily closed in the Roman Era. In the Venetian Times, the mines reopened and this small island prospered again. However, due to the frequent attacks of pirates and the suppression of the Ottomans, who later conquered the island, the mines had again to be closed for a long time.
