ISEO, LAKE OF, a lake in Lombardy, north Italy (anc. Locus Sebinus), at the southern foot of the Alps, between the provinces of Bergamo and Brescia. The Oglio enters the north end at Lovere and leaves the south end at Sarnico to join the Po. Area 24 sq.m., length 171 m., greatest width 3 m., greatest depth 984 ft., height of surface above sea-level 607 ft. It contains the island of Siviano, culminating in Monte Isola (1,965 ft.) crowned by a chapel, while to the south is the islet of San Paolo, occupied by the buildings of a small disused Franciscan convent and to the north the equally tiny island of Loreto, with a ruined chapel containing frescoes. At the southern end of the lake are the
small towns of Iseo (15 m. by rail from Brescia) and of Sarnico. From Paratico, opposite Sarnico, on the left bank of the Oglio, a railway runs in 6i m. to Palazzolo, on the main Brescia-Bergamo line. Towards the head of the lake, the deep wide valley of the Oglio is seen, dominated by the glittering snows of the Adamello (11,661 ft.). Along the east shore a fine carriage road as well as the railway runs from Iseo to the town of Pisogne (131 m.), on the north-east side of the lake.
