Laurium

Laurium or Lavrio (; ; before early 11th century BC: Θορικός Thorikos; from Middle Ages until 19th century: Εργαστήρι Ergastiri) is a town in southeastern part of Attica, Greece. It is the seat of the municipality of Lavreotiki. Laurium was famous in Classical antiquity for silver mining, which was one of the chief sources of revenue of the Athenian state. The metallic silver was mainly used for coinage. It is a sea port of much less importance than nearby Piraeus.
