strong and considerable city of Italy, belonging to the duchy of Milan, with a good castle, built in 1178 in honour of Pope Alexander III. This pope made it a bishopric, with several privileges and exemptions. Prince Eugene of Savoy took this city in 1706, after three days siege. The French took it in 1745; but the king of Sardinia, to whom it belongs by the treaty of Utrecht, retook it in 1746. The fortifications of the town are trifling, but the citadel is considerable. It is 15 miles south-east of Casal, 35 north-by-west of Genoa, and 40 south-by-west of Milan. E. Long. 8. 40. N. Lat. 44. 53. The country about this town is called the Alexandrin.
