Beyond Baratti sits Populonia, with its castle and ancient acropolis, famous as early as the Iron Age (900 BCE). It was one of the 12 most important cities in Etruria and the only one on the sea. Populonia has just 30 year-round residents, but 2500 years ago, it’s population was 40,000 and it was one of the main ports on the Mediterranean. Make sure to stop by the Buca delle Fate, a wonderful bay worth visiting, which gets its name from the Etruscan tombs in the rocks. For a more romantic landscape, you can instead follow the roads to Donoratico, Marina di Castegneto, and Marina di Cecina, which were the inspiration for many of Carducci’s poems.
