It lies some 426 km north-west of Bucharest, in the valley of the Somesul Mic river and it used to be the capital of the historical province of Transylvania.
The municipality (Municipiul Cluj-Napoca) has a population of 311,400. Finaly the population of the influence area (periurban area) counts over 400 thousand residents. According to an official in the City Hall, the total population of the city is high as 504,000, including students and other non-residents.
The municipal border covers a relatively small area, of 179,52 km2. According to estate experts, because of the development of the infrastructure, localities (comune) like Feleacu, Valcele, Martinesti, Jucu and Baciu will eventualy become neighbourhoods of the city, therefore enlarging its area.
