It originates in the Eastern Carpatian mountains where the two branches – White Tisza and Black Tisza – are united. Curving its way through the Great Plains of Hungary, it used to rule huge areas of land until the regulation of the riverways began in 1840. Pál Vásárhelyi prepared the plans. The River Tisza and the city of Szeged are inseparable. Fishermen’s inns offer fish from the Tisza with their fish specialty dishes.
