a town of the island of Sardinia, capital of a province of the same name, in the division of Cagliari, stands in the midst of salt marshes, about a mile from the left bank of the Tirsi, about 3 miles from the W. coast of the island, and 30 N.N.W. of Cagliari. It has a low and unhealthy situation, and a very desolate appearance, which is not at all in keeping with the turreted wall which surrounds the town, or the handsome houses which still bear the arms of the Spanish nobles who lived here when Sardinia was a dependency of Spain. It seems probable that in former times the salt marshes here were not so extensive as they now are; so that the site of the town would not have been originally an unfavourable one. Out of several churches, the only noteworthy one is the cathedral, a modern building, which contains several good paintings. There is an old palace, once the residence of the judges of Arborea, a convent, several schools, and an hospital. Manufactures of ironware, cutlery, arms, and other implements, are carried on. Pop. 6000.
