The Tuscan Plain (Piana Toscana) is a broad, fertile alluvial plain in central Italy, within the region of Tuscany. It lies between the Ligurian Sea to the west and the Tyrrhenian Sea to the south, framed by mountain ranges.
The plain’s rich soil and Mediterranean climate have supported agriculture for millennia, making it a historic heartland of Etruscan and Roman civilization. Today, it remains a key agricultural and tourist area.
