Kalocsa (Hungarian pronunciation; Croatian: Kaloča or Kalača; Serbian: Kaloča or Калоча; German: Kollotschau) is a town in Bács-Kiskun county, Hungary. It lies 142 km (88 mi) south of Budapest. It is situated in a marshy but highly productive district, near the left bank of the Danube River. Historically it had greater political and economic importance than at present. Kalocsa is the Episcopal see of one of the four Catholic archbishops of Hungary. Amongst its buildings are a fine cathedral, the archiepiscopal palace, an astronomical observatory, a seminary for priests, and colleges for training teachers. The residents of Kalocsa and its wide-spreading communal lands are chiefly employed in the cultivation of paprika, fruit, flax, hemp and cereals, in the capture of waterfowl and in fishing. Kalocsa is one of the oldest towns in Hungary. The present archbishopric, founded about 1135, is a development of a bishopric said to have been founded in 1000 by King Stephen the Saint. It suffered much during the 16th century from the invasions of Ottoman soldiers, who ravaged the country. A large part of the town was destroyed by a fire in 1875, before buildings were constructed of more fireproof materials and when many used open fires for heating and cooking.
