OMAGH, a market town and the county town of county Tyrone, Ireland, on the river Strule, 129¼ m. N.W. by N. from Dublin by the Londonderry line of the Great Northern railway, here joined by a branch from Enniskillen. Pop. (1901) 4789. The greater part of the town is picturesquely situated on a steep slope above the river. The milling and linen industries are carried on, and monthly fairs are held. The Protestant church has a lofty and handsome spire, and the Roman Catholic church stands well on the summit of a hill. A castle, of which there are scanty remains, was of sufficient importance to stand sieges in 1509 and 1641, being rebuilt after its total destruction in the first case. The town is governed by an urban district council.
