EISENERZ, an old mining town in Styria, Austria. It lies in a deep valley, tributary to that of the Enns and is dominated by imposing peaks, one of which, the Erzberg (5,03o ft.), to the south is connected with the town by a rack railway which descends to Vordernberg on the south side of the Erzberg. On this moun tain is quarried in the summer months the rich iron ore to which the town owes its prosperity. Nearly one million tons of ore, with a 35 per cent iron content, are raised annually, part of this output being handled in the iron and steel foundries of Vor dernberg and Eisenerz. The Gothic church of St. Oswald, founded in the 13th century and rebuilt in the 16th, is an interesting example of a mediaeval fortified church. Pop. (1920) 8,600.
