a town of Naples, in the province of Terra di Lavoro, 15 miles E.N.E. of Frosinone. It occupies a flat piece of ground, partly surrounded by the Liris, where that river issues from a narrow glen; and immediately behind the town rises a rocky hill crowned with old Cyclopean walls and Gothic towers. The streets are broad, well paved, and lined with large and substantial houses. There are here a fine cathedral, several churches and convents, a school, hospital, and almshouses. Woollen cloth and paper are manufactured. Sora was originally a Volscian city, and probably the furthest north of their possessions. It was seized by the Romans in 345 B.C., and subsequently made a colony; but in 315 the inhabitants rose against the Romans, and joined their enemies the Samnites. It was not finally secured as a Roman colony till the end of the second Samnite war in 303. After this period its history is of no importance; but it is frequently mentioned as a quiet country town. A few Roman remains have been preserved. Sora was the birth-place of Cardinal Baronius, the eminent Roman Catholic historian. Pop. 8000.
