History

St. Helena was first inhabited by a native American group known as the Wappo people. They spoke Yukian and are believed to have first settled in St. Helena as early as 2000 B.C. The Wappo name for the area is Anakotanoma, meaning ‘Bull Snake Village’.

The area was likely named after a nearby mountain known as Mount St. Helena.

The locale became renown when White Sulphur Springs was discovered in 1848 and established an operating resort in 1852. During the later 19th century, affluent San Franciscans traveled here by steamer across the Bay, and then four miles by stage and later by train. At its prime, California’s oldest resort was able to accommodate 1000 guests in its grand hotels which were later lost to local wildfires. The site is recognized as a National Historic Landmark.

The town of St. Helena was founded by Henry Still, who bought land from the Edward Bale family in 1855. By 1858 there was a school house and a little Baptist church. Four years later Professor William Brewer of the Whitney party called it a “pretty little village with fifty or more houses . . .nestled among grand old oaks.” It officially became a town on March 24, 1876, and by 1886 the population grew to 1,800 inhabitants. Shortly after in 1868, the first railroad was created in St. Helena allowing for shipment of resources such as fruit and mining products. The newly built train tracks also brought in tourists.

Ellen White, co-founder of the Seventh-day Adventist Church, had a home called Elmshaven near St. Helena, beginning in 1900. She died there in 1915, and the site is now a National Historic Landmark. Both the Beringer Vineyards and the Charles Krug Winery are California Historical Landmarks.

St. Helena’s community center was built as a Carnegie library; it served as the city library from 1908 to 1978.
