Aquitaine, archaic Guyenne/Guienne, is one of the 26 regions of France, in the south-western part of metropolitan France, along the Atlantic Ocean and the Pyrenees mountain range on the border with Spain. It comprises the 5 departments of Dordogne, Lot et Garonne, Pyrénées-Atlantiques, Landes and Gironde. In the Middle Ages Aquitaine was a kingdom and later a duchy, with boundaries considerably larger than the modern ones.
