Aquitaine

Biarritz, France

Aquitaine, former région of France. As a région, it encompassed the southwestern départements of Dordogne, Gironde, Landes, Lot-et-Garonne, and Pyrénées-Atlantiques. In 2016 the Aquitaine région was joined with the régions of Poitou-Charentes and Limousin to form the new administrative entity of Nouvelle-Aquitaine. The present-day région of Nouvelle-Aquitaine roughly matches the western half of the historical region of Aquitaine.
