JASZ-BERENY, a town of Central Hungary, situate on both sides of the River Zagyva, a tributary of the Theiss, 13 miles distant from Jasy-Apathi, and 41 miles E. of Pesth. It contains a large Roman Catholic besides several other churches, a Franciscan convent, a gymnasium, and council-hall. Tradition points out an old tomb on an island in the Zagyva as that which contains the bones of Attila the Hun, but there is not the slightest historical probability that this is really his sepulchre. Jasz-Bereny has markets for corn, cattle, and horses. Pop. (1851) 16,573.
