Croatia is a Central European and Mediterranean country, bordering Slovenia in the west, Hungary in the north, Serbia in the east and Bosnia and Herzegovina in the south; the country also has a long maritime border with Italy in the Adriatic Sea. These borders total 2,028 km altogether. Croatia has an unusual shape (similar to a croissant) that is unlike any other country in the world, which comes as a result of five centuries of expansion by the Ottoman (Turkish) empire towards Central Europe (although Croatia was never conquered by the Turks).
Croatia covers a land area of 56,691 square kilometres and has a population of about 4.29 million people (2011 census). Almost 90% of the population is Croat (the majority of whom are Roman Catholics), but there are also Serbian, Bosnian, Hungarian and Italian minorities. The main population centres are Zagreb, the capital (with a population of just under 800,000), Osijek in the northeast (population: 107,000), and the ports of Rijeka (population: 128,000) on the northern part of the coastline, and Split (population: 178,000) towards the south. Other well known towns include Dubrovnik, Makarska, Porec, Rovinj, Opatija, Zadar and Sibenik.
