Laurium, a Greek city southeast of Athens, has been famous since ancient times for its silver mines. The mines were exploited until the 20th century by French and Greek companies for lead and manganese. In the 19th century, the company held a concession from the Greek government. She also participated in the construction of a railway in Attica.
