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


Onești in 1965

The locality was documentary attested as a village on December 14, 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.[3]

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.[4]

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


Onești is located in the Tazlău-Cașin Depression of the Eastern Carpathians at an average altitude of 210 metres (690 ft).[5] 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.
