History

edit
Onești in 1965

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.[4]

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.

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.[5]

Geography

edit

Onești is located in the Tazlău-Cașin Depression of the Eastern Carpathians at an average altitude of 210 metres (690 ft).[15] 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.[16]

Climate

edit

The climate of Onești is temperate-continental, with temperatures ranging from -25 °C (though in recent decades this value is rarely recorded) in winter to +35 °C in summer, with an average annual temperature of 9.2°C, and annual precipitation totaling 654 mm. The most frequent winds blow from the west and south-west. The vegetation is specific to the temperate-continental zone: conifers, deciduous trees, and climbing plants, as well as rare plants found in the Perchiu reserve (SCI site), a protected natural area included in the site of community importance - Dealul Perchiu.[17] The microclimate of Onești is significantly shaped by the foehn effect, a consequence of the city's location within the Tazlău-Cașin Depression at the leeward eastern foothills of the Eastern Carpathians. When prevailing westerly air masses ascend the western slopes of the Ciuc and Berzunți mountains, they cool and shed their moisture as precipitation.

The highest recorded temperature is +40.8 °C (105.4 °F), on 5 July 1916, and the lowest is -29.6 °C (−21.3 °F) on 25 January 1942. On the 17th December 1989, Onești recorded a temperature of 23.3 °C (73.9 °F), just 0.1°C lower than Romania's national record of 23.4 °C (74.1 °F), set at Câmpina in 1985.[18][19][20]
