The Archaeological Museum of Lavrion shows much of the story of these mines.

It is about 60&nbsp;km southeast of Athens city center, on a bay overlooking the island of Makronisos (ancient Helena) to the east. The EO89 road runs through Lavrio.

==History== {{further|Thoricus|Mines of Laurium}} thumb|left|upright=1.2|Map of the mines of Laurion thumb|Ruins of the ancient theatre at Thorikos thumb|Archaeological Museum of Laurion The modern town of Lavrio is at the site of the ancient village of Thoricus; its name is taken from that of the entire region of the Mines of Laurium.

The earliest evidence for mining dates to the beginning of the Bronze Age, ca. 3200 BC.<ref>{{cite web|url=http://greece.greekreporter.com/2016/02/17/newly-discovered-greek-silver-mine-rewrites-history/|title=Newly Discovered Greek Silver Mine Rewrites History - GreekReporter.com|website=greece.greekreporter.com|access-date=20 April 2018}}</ref>

Systematic exploitation of mineral resources seem to have begun in the 6th century BC under Peisistratus.<ref>{{cite journal|doi=10.1111/arcm.12839 |title=Other ways to examine the finances behind the birth of Classical Greece|last1=Wood|first1=J.R.|journal=Archaeometry|year=2022|volume=65 |issue=3 |pages=570–586 |s2cid=253075525 |url=https://discovery.ucl.ac.uk/id/eprint/10159871/ |doi-access=free}}</ref> After the battle of Marathon, Themistocles persuaded the Athenians to devote the anticipated revenue derived from a major silver vein strike in the mines of Laurion circa 483 BC to expanding the Athenian fleet to 200 triremes, and thus laid the foundation of the Athenian naval power. The mines, which were the property of the state, were usually farmed out for a certain fixed sum and a percentage on the working; slave labour was exclusively employed.{{sfn|Chisholm|1911}}

Towards the end of the 5th century, the output fell, partly owing to the Spartan occupation of Decelea. But the mines continued to be worked, though Strabo records that in his time the tailings were being worked over, and Pausanias speaks of the mines as a thing of the past. The ancient workings, consisting of shafts and galleries for excavating the ore, and washing tables for concentrating the ore, are still visible in places.{{sfn|Chisholm|1911}}

The mines were reworked in the late 19th century by French and Greek companies, but mainly for lead, manganese and cadmium.{{sfn|Chisholm|1911}} In 1896 a strike from the miners was violently confronted by the mining company's guards resulting in the death of two workers. The miners responded by destroying the company's offices and killing the guards. The government then sent police forces to support the company's interests against the strikers. Further clashes between workers and the police occurred to which the government replied by sending the military against the striking workers resulting in more workers' deaths. The strike ended violently with most of the strikers' demands not being fulfilled and with a military force being permanently established to patrol the miners.<ref>{{Cite web |date=30 April 2017 |title=Η απεργία των μεταλλωρύχων στο Λαύριο το 1896.
