Important Sights

Cluj-Napoca is the second most populous city in Romania situated in the northwestern part of the country. Geographically, it is roughly equidistant from Bucharest (441 km), Budapest (409 km) and Belgrade (465 km). Located in the Someşul Mic River valley, the city is considered the unofficial capital to the historical province of Transylvania. The past history of Transylvania is strongly connected to the myth of count Dracula, a legend promoted by Bram Stoker’s well-known novel. The source of inspiration of the novel seems to be the figure of a Romanian prince, “Vlad the Impaler”, ruler of Vallachia, who was born in Sighişoara, a nice historical town in Transylvania. Prince Vlad is revered as a folk hero by Romanians for driving off the invading Turks, but he is also known for the fact that he used to punish thieves, criminals and anyone else he considered useless to humanity, but also the boyars or other political rivals who were against his policy, by impaling them on a sharp pole.

The present name of the city, Cluj-Napoca, was established on October 16th 1974, on the occasion of the celebration of the first documentary attestation of the city as a “municipium”. The name derives from the ancient Dacian name Napuca and the Latin name Clus, meaning “closed”, with reference to the hills around the city. The population of the city was, in 2014 amounted to 350,000 inhabitants. However, this number does not include the floating population of students and other non-residents—an average of over 90,000 people each year. The city spreads out from St. Michael’s Church in Unirii Square, built in the 14th century and named after the Archangel Michael, the patron saint of the city.

Cluj-Napoca is also the born place of János Bolyai, Transylvanian mathematician, known for his work in non-Euclidean geometry. Bolyai’s work was published in 1832 as an appendix to a math textbook by his father Farkas Bolyai. Independently from János Bolyai, N.I. Lobachevsky published in 1929 a similar work on non-Euclidean geometry. Today, these essential contributions are known as Bolyai-Lobachevsky geometry.

Today, the city is one of the most important academic, cultural, industrial and business centers in Romania. Among other institutions, it hosts the country’s largest university, Babeş-Bolyai University, with its famous botanical garden. Notice also, that  Cluj-Napoca is quickly becoming Romania’s technopolis, since a large number of IT&C companies are operating here.
