History
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.[2]
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[3] shortly after the Romanian Revolution.
