Onești

Onești sits where four rivers meet—Trotuș, Cașin, Oituz, and Tazlău—in a natural depression about 210 meters above sea level. The town grew into an industrial center with large petrochemical plants that shape its appearance and economy today.

The settlement was first documented in 1458 as a small community along the rivers. The town's character changed dramatically in the 1950s when communist authorities built large petrochemical factories, turning it into an industrial hub.

The nearby Borzești Church shows the religious traditions of the region and continues to serve as a gathering place for locals today. Its construction methods and style reflect how communities built lasting structures during the late medieval period.

The town connects to other regions via European road E574 and national roads DN11A and DN12A, which lead to Bucharest and Transylvania. Visitors can easily reach the riverbanks and nearby villages on foot or using local transport.

Archaeological finds above the Malu district show that people lived along the Cașin river during the Neolithic period thousands of years ago. This early settlement pattern reveals why the riverside location has drawn communities for so long.
