Marble Quarries of Marathi
For some reason, you’ll rarely hear the Marathi quarries mentioned, despite the fact that the marble used to sculpt the Venus di Milo came from this very site, and it’s known as possibly the most ancient marble mines in the world. Wear comfortable shoes and bring a flashlight to properly explore the mine shafts. It’s isn’t really set up as a tourist destination; in fact, there is no signage or explanatory material. But given its history and significance as the primary source of material in building the Parthenon and many other Greek landmarks, it’s certainly worth a look.
