(Flem. Doornik), a town of Belgium, capital of an arrondissement in the province of Hainault, on the Scheldt, 27 miles N.W. of Mons. It is divided into two parts by the Scheldt, which is spanned by several bridges and lined with spacious quays. The old town stands on the left bank, and the new town, which is distinguished by its neat regular streets and well-built houses, on the right. In the former, the most remarkable building is the cathedral, a large, ancient, and beautiful edifice in the Gothic style, with five pointed towers. The interior is very majestic, especially the choir, and contains some fine paintings by Rubens, sculptures in marble, and interesting ancient remains. Near the cathedral is the market-place, in which stands the belfry, a lofty tower of unknown origin, but supposed to have been part of an old castle in the thirteenth century. Several of the churches of Tournay are ancient and interesting; and there is also an ancient convent, now used partly as a town-hall and partly as a museum; a large and imposing guard-house; and a concert-room with a colonnade and dome. The town contains courts of law, a public library, atheneum, theatre, picture-gallery, school of arts, episcopal seminary, primary schools, hospitals, &c. It is enclosed by strong fortifications, and defended by a well-constructed citadel. Many and important manufactures are carried on here, chiefly of woollen and cotton cloth, hosiery, linen, carpets, hats, paper, leather, porcelain, pottery, bronze articles, cutlery, &c. The trade of the place is also very considerable, as ships of 150 tons burden can ascend the river to Tournay, and railways connect it with all the chief towns of Belgium and France. Tournay is supposed to be the Civitas Neriviorum of Julius Caesar, and at a later period it was called Tornaeus. It was one of the first places conquered by the Franks, and Clovis made it for a time his capital. In modern times, standing as it does on the very frontier between Belgium and France, Tournay has very frequently been besieged and taken in the various wars that have desolated this part of Europe.
