Piedmont (; Piedmontese and ; ) is one of the 20 regions of Italy. It has an area of 25,402 square kilometres (9,808 sq mi) and a population of about 4.6 million. The capital of Piedmont is Turin. The main local language is Piedmontese. Occitan is also spoken by a minority in the Occitan Valleys situated in the Provinces of Cuneo and Turin. Franco-Provençal is also spoken by another minority in the alpine heights of the Province of Turin. The name Piedmont comes from medieval Latin Pedemontium or Pedemontis, i.e., ad pedem montium, meaning “at the foot of the mountains” (attested in documents of the end of the 12th century).
