Rijeka is the principal seaport and the third-largest city in Croatia. It is located in Primorje-Gorski Kotar County on Kvarner Bay, an inlet of the Adriatic Sea and has a population of 128,624 inhabitants.Historically, because of its strategic position and its excellent deep-water port, the city was fiercely contested, especially among Italy, Hungary (serving as the Kingdom of Hungary’s largest and most important port), and Croatia, changing hands and demographics many times over centuries. According to the 2011 census data, the majority of its citizens are Croats, along with a large minority of Serbs, and smaller numbers of Bosniaks and Italians.
Rijeka is the main city and county seat of the Primorje-Gorski Kotar County. The city’s economy largely depends on shipbuilding (shipyards “3. Maj” and “Viktor Lenac Shipyard”) and maritime transport. Rijeka hosts the Croatian National Theatre Ivan pl. Zajc, first built in 1765, as well as the University of Rijeka, founded in 1973 but with roots dating back to 1632 School of Theology.
