At the site of Marathi, some 5 kilometers northeastern to Paroikia, the visitor may see the ancient quarries of the “Parian stone”. Big galleries, some 200 meters long, go deep in the soil and have three entrances. At the left side of the southern entrance there is a nice Hellenistic bas-relief with interesting carving and a partly preserved inscription. The sculpture is dedicated to the Nymphs, who were worshipped here; hence, the name “Quarry of the Nymphs”. There are also preserved several construction as support columns, staircases, retaining walls and a considerable number of pieces of marble.

During the Byzantine times the extraction stopped, as art followed a different direction and the marble was not used too much. Later on, during the domination of the Francs and mainly in the period of Somaripa, the trade of marble flourished again. The precious material was exported in several places of the Mediterranean and above all in Venice.
