a town of France, department of Ariège, on the Lers, 14 miles E. of Pamiers. It is clean and well built, and contains several squares adorned with trees and fountains. It was formerly surrounded by ditches, but these have been filled up, and are now used as boulevards. The principal buildings are,—the parish church, a town-hall, a communal college; an hospital, with several schools attached to it; a handsome stone bridge of seven arches; and a square tower, all that remains of its ancient castle. Coarse woollen stuffs, linen, cotton, flannel, worsted, and soap are manufactured here; and there is a considerable trade in grain, and in the iron which is obtained in considerable quantities in the neighbourhood.
