a market-town and parliamentary borough of Ireland, is situate on the Lagan, partly in Upper Castle-reagh barony, county of Down, and partly in Upper Massereene barony, county of Antrim. 8 miles S.S.W. from Belfast by the Ulster Railway. Having been destroyed by fire in 1707, the town has a modern aspect. It consists chiefly of a long irregular street of houses, well built, and roofed with slate. It is paved, lighted with gas. At the end of the main street stands the cathedral for the united diocese of Down and Connor—a picturesque edifice, surmounted by an octagonal spire, of date 1807, and containing the tomb and monument of its bishop, Jeremy Taylor, who died at Lisburn in 1667. There are also a chapel of ease, a Presbyterian church, a Roman Catholic chapel, and meeting-houses for Methodists and Quakers. Besides several schools, it has an institution endowed by John Hancock, for the maintenance and education of forty Quaker children, an infirmary for the county of Antrim, a union workhouse, and a linen hall. The gardens of the old ruined castle are open to the public. Its manufactures are—linen thread, damasks, muslins, and diapers, and flax-spinning and bleaching are extensively carried on. Great facilities for trade are afforded by its position on the railway and on the river, and its weekly markets on Tuesday are well supplied with manufactured and agricultural produce. Its fairs are held on the 21st of July and the 5th of October. It is the seat of courts for Kilultagh Manor, courts leet, and petty sessions. The borough returns a member to parliament, and gives the title of Viscount to the family of Vaughan. Lisburn was founded by Viscount Conway, in 1627, beside the castle which his ancestor Sir Fulk Conway had erected in 1610, and was first inhabited by English and Welsh settlers. In 1641 it was laid in ashes by the Irish insurgents. Huguenot families, fleeing thither after the revocation of the Edict of Nantes, imported the linen manufacture. It was again burnt in 1707, but rapidly resumed its prosperity, and is now in a flourishing condition. Pop. (1851) 6569.
