an ancient town of Ireland, county of Waterford, on the right bank of the Blackwater, 30 miles N.E. by E. of Cork, and communicating with Youghal by canal and the Blackwater. It stands on an elevation overlooking the river, having on the E. the cathedral, an elegant building with a tower and spire, and on a rocky precipice on the W. the massive old castle. The Blackwater is here crossed by a fine bridge, the centre arch of which has a span of 100 feet. Its chief buildings, besides the above-named, are—a Roman Catholic chapel, a Presbyterian place of worship, a classical and other schools, a fever hospital, and several almshouses in behalf of aged Protestant soldiers. Trade is here confined to the agricultural produce of the district, and slates from neighbouring quarries. Lismore is said to have originated from a monastery founded here by St Carthagh in the seventh century. Two centuries later it was several times pillaged by the Danes. In the thirteenth century King John of England founded the castle which, with the town, suffered much during the rebellion of 1641. From that time the town long continued in a state of decay, until it became the property of the Devonshire family, when great improvements were made. The castle is now in complete repair. Pop. (1851) 2340.

(Gaelic, Leosmore, "The Great Garden"), an island off the W. coast of Scotland, in the county of Argyll, is situate at the mouth of Loch Linne, about 7 miles N.N.W. from Oban. Its greatest length is about 10 miles, its average breadth 1½ miles, and its area about 8000 acres. The greater part of the island is under cultivation, and the remainder, though rocky, is covered with a rich green sward, variegated by small clumps of trees. Herring-fishing is carried on by the inhabitants; and limestone is exported. In ancient times the bishops of Argyll inhabited the Castle of Lismore, now in ruins, and were on that account sometimes styled Episcopi Lismorensis. There are also the remains of the small Cathedral of St Moluag, the chancel of which is used as a parish church. Pop. (1851) of the united parishes of Lismore and Appin, 4097.
