Brief History

Beringer Vineyards in the Napa Valley, California.
The historic Beringer Vineyards - a large winery in St. Helena in the Napa Valley of northern California was founded in 1876. 

St. Helena was initially inhabited by the native Wappo people who spoke in the Yukian language and are believed to have originally settled in the area as early as 2000BC. Anakotanoma, the local Callajomanes tribelet village, was located close to the confluence of the Napa River and the Sulphur Creek. It is believed that the town was likely named after Mount St. Helens. In 1834, the area was settled as a part of General Vallejo’s land grant. Several people from faraway lands and all walks of life started relocating here, and the new settlers began planting vineyards and making wine in the 1860s. In 1868, the first railroad was built to transport food, grain, and other mining products. On March 24, 1876, St. Helena was officially incorporated as a town, and by 1886 the population grew up to 1,800 inhabitants. On May 14, 1889, the town of St. Helena was reincorporated as the city of St. Helena.
