KASCHAU (Hung. Kassa, Lat. Cassoria), a royal free city of Hungary, finely situated at the confluence of the Hernad and Csermel, in the county of Abaujvar, 125 miles N.E. of Pesth. It is enclosed by vineyards, at an elevation of 1060 feet above the sea-level, in N. Lat. 48.39, E. Long. 21.16. The town, which is nearly oval in shape, is well built, its streets are regularly laid out, and it is adorned with squares, and handsome buildings. The cathedral, called Elizabeth-Pfarrkirche, with its copper-covered tower, and fine internal decorations, is as old as the middle of the fourteenth century, and is the best specimen of Gothic ecclesiastical architecture in Hungary. There are thirteen Catholic, and two Lutheran churches, besides the various government houses, bishop's palace, schools, museum, library of 10,000 vols., infirmary, theatre, and aristocratic mansions. The manufactures consist of leather, hats, tobacco, woollen cloth, paper, and gunpowder. There are quarries of stone and slate, and works for making tiles and bricks. The chief trade of Kaschau is in wine. The nobility and upper classes resort to the town in the winter time. Latin, as well as German, is spoken, and both in great purity. Pop. (1851) 13,034.
