a territory or county of France, in the province of Gascony, which is now included in the department of the Upper Pyrenees. It is bounded on the east by the valley of Aure, the vicounty of Neubouffia, Riviere Verdun, and Pardiac; by Bearne on the west; on the south, by the valleys of Brotou and Penticouf in Arragon; and on the north, by the county Riviere-Bas incorporated with Armagnac. It is 40 miles long from north to south, and 30 in breadth from east to west. It is divided into three parts, the mountains, the plains, and the Rustan. The mountains are enclosed between those of the valley of Aure on the east, those of Arragon on the south, and of Bearne on the west. This part contains two principal valleys, Lavedan and Barege. The valley of Bigorre is of an oval form, and has the hills of Rustan on the east. The remarkable towns are Tarbes the capital, Bagnères, Lourd, &c. The mountains are a barrier between France and Spain, and there are four different passages which the inhabitants are obliged to guard. Bigorre yields marble, jasper, stone, and flate; there are also mines of several sorts, but they are not worked. The rivers are the Adour, the Elches, the Arroset, and the Gave of Lavedan; there are also three lakes.
