Béarn is one of the traditional provinces of France, located in the Pyrenees mountains and in the plain at their feet, in Southwestern France. Along with the three Basque provinces of Soule, Lower Navarre and Labourd, the Principality of Bidache, as well as small parts of Gascony, it forms the current Pyrénées-Atlantiques department. The capitals of Béarn were successively Beneharnum, Morlaàs, Orthez and then Pau.
