or Placentia, a town of Spain, Extremadura, in the province of Cáceres, nearly encircled by the clear river Xerte, in a beautiful valley between the snowy Sierras de Bejar and de la Vera, 120 miles W.S.W. of Madrid. The ancient walls of the town, with their strong semicircular towers, the ruined castle, the long aqueduct raised on 80 arches, and the three picturesque bridges that cross the river, combine with the scenery to give Placentia a very beautiful aspect. The cathedral, built in 1493, is a fine Gothic edifice, though some parts are unfinished, and others have been altered for the worse. It contains several fine pictures and monuments. There are here several other churches, convents, a bishop's palace, a large town-house, several schools, and a college (seminario conciliar), connected with the university of Salamanca. Oil, soap, leather, hats, woollen, linen, and hempen stuffs are manufactured. Placentia was plundered by Scult in 1809, a calamity from which it has never recovered. Pop. 6800.
