a province of Sardinia, but formerly an independent principality, now reduced to the condition of a mediatised state, to the prince of which his rents are preserved. It extends over fifty-five square miles, and contains two cities, with about 6000 inhabitants. The district is sheltered from cold winds, which makes the climate like that of the tropics; and the productions of the soil are similar, fruit being abundant, but corn deficient; and flesh rather more so. It was seized by France in 1792, and added to one of her departments; but, by the congress of Vienna in 1815, it was transferred to Sardinia. The chief place, of the same name, is situated on a tongue of land running into the sea. The walls and gates are dilapidated. It contains 1250 inhabitants, employed in petty trade. Long. 7° 23' E.
