Onești

Onești (Romanian pronunciation: [oˈneʃtʲ]; Hungarian: Ónfalva), formerly known as Gheorghe Gheorghiu-Dej, is a city in Bacău County, Romania, with a population of 34,005 inhabitants as of 2021. It is situated in the historical region of Moldavia.

Administratively, the villages of Slobozia and Borzești form part of Onești.

The locality was documentary attested as a village on 14 December 1458. In 1952, the communist authorities decided to build a large petrochemical industrial platform (Borzești Petrochemical Plant) and a new related city in the area of Onești and Borzești villages. Borzești, according to legend, was the birthplace of Stephen III of Moldavia. It is the site of the Borzești Church, which was built on his orders in 1493–1494.

At the death of the Communist leader Gheorghe Gheorghiu-Dej in March 1965, Onești was renamed Gheorghe Gheorghiu-Dej, but the name was changed back in 1990 shortly after the Romanian Revolution.

Above the borough Malu, on the right-hand side of the river Cașin, were discovered archaeological fragments from a settlement dating from the Neolithic Age.

At the 2011 census, Onești had 39,172 inhabitants, of which 90.29% were Romanians, 1.39% Roma, 0.53% Hungarians, and 0.13% Greeks. According to the 2021 census, the population of the municipality of Onești amounts to 34,005 inhabitants, a decrease compared to the previous census in 2011, when 39,172 inhabitants were recorded. The majority of the residents are Romanian (79.75%), while for 19.77%, their ethnic affiliation is unknown. From a confessional point of view, the majority of inhabitants are Orthodox (69.43%), with a Roman Catholic minority (7.87%), and for 20.69%, their confessional affiliation is unknown.

Borzești is a neighborhood in the southeast of Onești, under separate administration until 1968. The Borzești Petrochemical Plant is located there.

Onești is located in the Tazlău-Cașin Depression of the Eastern Carpathians at an average altitude of 210 metres (690 ft). It lies at the confluence of the rivers Trotuș, Cașin, Oituz, and Tazlău, some 60 km (37 mi) southwest of the county capital, Bacău. The city is crossed by the European road E574 and by the national roads DN11A and DN12A that connect it to Bucharest, to the northern part of the country, and to Transylvania. Rail connections are made through the Căile Ferate Române network, and the proposed A13 Brașov–Bacău Motorway will link the city to the rest of Romania's highway network as a second connection to the country's major cities.
