a town of South France, department of Hautes Pyrénées, on the right bank of the Gave-de-Pau, 24 miles S.E. of Pau. It is built on a steep elevation, which rises to the height of 511 feet, and is crowned by a fortress formerly possessed by the counts of Bigorre. The streets are as well laid out as the irregular nature of the ground will admit. Manufactures of handkerchiefs and flax are carried on, as well as a general trade in agricultural produce. Some remains of Roman fortifications are found here, and in the vicinity are several curious grottos. While in the possession of the English in the fourteenth century, it formed the centre point of their military operations, but was evacuated by them shortly after the treaty of Breigny in 1360. Pop. (1851) 4500.
