The ancient marble quarries can be found in Marathi, Paros.

The ancient quarries were not only aboveground but also underground with the total length of the galleries reaching 190 meters. From here the famous Parian marble was mined, also known as rogue stone or garnet. The name garnet is "lychnitis" in Greek and it acquired it because of the lamps--then called "lychnies"-- used by the workers to see when coal mining. The Parian marble was of excellent quality, with an almost transparent white color. Using this, several important works of antiquity were created such Afrodity of Milos/ Venus de Milo, Hermes of Praxiteles, Nike of Samothrace and buildings such as the temple of Zeus at Olympia, Delphi temples and more.

Today the mines have seized to operate but they still are an impressive sight. You can still see the supporting columns, the protective walls and the stairs in the tunnels, while on the walls there are engraved inscriptions of Greek and foreign visitors. Of particular interest is an inscription on the rocks depicting the Olympian gods, whisch seems to be dedicated to the Nymphs according to the inscription at its bottom: "Adamas ODRYSIS NYMFAIS". The inscription on the rock is dated around 350 BC and believed to be associated with the ancient name of the quarry as "Quarry of the Nymphs."
