NAVAN, a market-town of Ireland, county of Meath, pleasantly situated on a hill at the confluence of the rivers Boyne and Blackwater, 28 miles N.W. of Dublin. The town is not well built; and the principal streets, of which there are four, though straight, are not clean. A bridge over the Boyne connects it with the suburb of Athlumney, and another over the Blackwater with that of Donaghmore. The parish church is a neat building, erected in 1818; and there is also a fine Roman Catholic chapel. There are also a court-house and market-house, bridewell, cavalry barracks, infirmary, dispensary, fever hospital, union workhouse, Roman Catholic convent and diocesan seminary, and national and other schools. It is connected with Drogheda by a railway and canal, by means of which it carries on some trade, chiefly in corn and other agricultural produce. There are in the town several flour, flax, and paper mills, a tannery, brewery, and two distilleries. Previous to the union, Navan returned two members to the Irish Parliament. Pop. 3626.
