Campan, a town of France, in the department of Hautes-Pyrenees, in the valley of the same name, 18 m. S. E. of Tarbes; pop. about 3,700. The valley is bounded by Mont Aigre, traversed by the river Adour, contains the ancient convent of Medous, the priory St. Paul, and the village l'Esponnes. It is celebrated for its picturesque scenery, for its stalactite grotto, and for its quarries of marble, which extend along the Adour and the road leading to Ba-gneres de Bigorre. The finest of these are the green and flesh-colored varieties, with red and white veins, known as the Campan marble, and the blood-red, or Griotte, full of fossilized shells, the spirals of which are disclosed in cutting. Knitting the fine wool of the Pyrenees, brought from Spain, gives employment to many females. Among the articles produced are shawls and scarfs of woollen gauze, as thin as lace. The so-called crepe de Bareges is also made here. Jean Paul Richter's Campaner-thal was inspired by the beauties of this valley.
