a town of Naples, in the province of Naples, on the shore of the Bay of Naples, 4 miles S.E. of the capital, with which it is connected by railway. It contains a royal palace, which was formerly used as a museum for the antiquities of Herculaneum and Pompeii. These, however, have been removed to Naples; and the palace has thus lost its chief attraction. It still possesses, however, some good pictures by modern French artists. Portici is a favourite resort during the autumn of the higher classes of Neapolitans. It has a harbour protected by a mole, a church, convent, barracks, and ribbon manufactory. Fishery and the coasting trade are actively carried on here. Pop. 6200.
