Ivre'a,

Ivre'a, a town of Piedmont, on an eminence at the southern end of the Val d'Aosta, 38 miles NNE. of Turin by rail. Founded in accordance with an injunction contained in the Sibylline Books about 100 B.C., it has a cathedral which is supposed to occupy the site of a temple to Apollo. It was the seat of a Longobard duchy, and under the Carlovings of a marquisate. One of the marquises of Ivrea, Berengar II., became titular king of Italy (q.v.) in the 10th century, and his grandson founded the line of the dukes of Burgundy. Incorporated with the empire in 1018, the town and marquisate were given by Frederick II., in 1248, to the House of Savoy. Pop. 5883.
