Béarn is bordered by Basque provinces Soule and Lower Navarre to the west, by Gascony (Landes and Armagnac) to the north, by Bigorre to the east, and by Spain (Aragon) to the south.
Today the mainstays of the Béarn area are the petroleum business, the aerospace industry through the helicopter manufacturer Turbomeca, tourism and agriculture. Pau was the birthplace of Elf Aquitaine, which has now become a part of Total petroleum company.
In Alexandre Dumas's The Three Musketeers series, the protagonist d'Artagnan was from Béarn (he mentions having attended his father's funeral there in the second book, Twenty Years After). That d'Artagnan is usually referred to as a Gascon is neither surprising nor incorrect, as Béarn is sometimes considered a part of Gascony.
