Once called Aurina or City of Gold, Saturnia is famed to be Italy’s oldest city and it embraces its past in every breath.
In the main piazza, you can run your hands over Roman tombstones or wander through the streets seeking Etruscan columns and thousand-year-old bathes until you come to an archway that was literally a door to the Roman Empire and the beginning of the long road to the capital.
Saturniais best known for its hot springs, which are located outside of the town, but the town itself deserves a visit too.
