or Piogredol, a town of the kingdom of Sardinia, capital of a province of the same name, in the division of Turin, stands near the foot of the Alps, on the Chisone, 21 miles S.W. of Turin. It is surrounded by a wall of no great strength; and though irregularly and not very well built, contains several squares, one of which, the Piazza d'Armi, is large and handsome. There are here a fine modern cathedral, several other churches, numerous convents, a town-hall, theatre, college, hospital, and barracks. Manufactures of iron, cloth, paper, leather, and silk are carried on; and there is a considerable trade in these articles, as well as in corn, wine, spirits, &c. Pinerolo, along with Fenestrelles, Oulx, Cesana, and the surrounding country, though originally a part of Piedmont, was in the possession of France from 1631 till the peace of Utrecht in 1713. It was once very strongly fortified; but its defences were blown up by the French in 1713. Pop. 14,000.
