The Ancient White Marble Quarries of Paros
The ancient marble quarries on the Island of Paros were in operation from the Early Cycladic period (3,200 BC) until the 19th century. Their golden era was from the 7th century BC to the 3rd century AD and is mainly associated with the extraction of the highly translucent lychnites marble from the underground galleries of the Nymphs’ and Pan’s quarries.
