Water is the essence of Kvarner, and the region's largest city expresses this simply. Whether in Croatian or Italian (Fiume) the translation of the name to English is the same: river. Although the history of Croatia's third city goes back to the days of Imperial Rome, modern Rijeka evolved under the rule of Austria-Hungary. The historic core retains vestiges of the old Habsburg monarchy from the time when Rijeka served as the empire's outlet to the Adriatic. During the 1960s, under Yugoslavia, the suburbs expanded rapidly. Rijeka is the country's largest port, with a huge shipyard, massive dry-dock facilities, refineries, and other heavy industries offering large-scale employment. Since the breakup of Yugoslavia, however, Rijeka's role as a shipping town has declined significantly. Much business shifted north to the smaller Slovene ports during the crippling wars of the 1990s, and although some has returned, the volume remains less than half that seen in 1980.
