Valle d’Aosta is a recognized region in Italy.
Given the prevalence of the French language, the region holds a distinctive position with the official designation of Autonomous Region of Valle d’Aosta (Italian: Regione Autonoma Valle d’Aosta, French: Région Autonome Vallée d’Aoste).
The administrative hub is situated in the city of Aosta.
Historically, this territory was inhabited by the Celtic Salassi tribe and was later taken over by the Romans. In the 5th century, following the decline of the Western Roman Empire, the area became part of the Burgundian and Frankish realms. By the 11th century, the territory was under the domain of the Savoy dynasty. It was designated as an autonomous region in 1945.
