Vilnius is located in the Lithuanian Lake District, at the confluence of the Neris and Vilia Rivers. It is the capital city of Lithuania, as well as its main industrial centre, educational and cultural centre, as well as the largest transportation hub. The unforgettable character of Vilnius was created throughout the years by various nationalities and ethnic minorities living with the Lithuanians, such as the Polish, the Russian, the Belarusian, the Jews and others. The city constitutes a unique complex of architectural and artistic monuments representing almost all European styles, from Gothic to modern times (the Old Town of Vilnius was inscribed on the UNESCO World Heritage List in 1994). Vilnius is also the main centre of Polish science and culture in Lithuania, with the Polish University in Vilnius, Association of Polish Scientists in Lithuania, the Polish Theatre in Vilnius and the House of Polish Culture all located there.
