It centers on an 1885 Victorian wood-frame residence built by Robert Pratt, plus a tank house and a 1902 office-library-vault building.","why_significant":"The property was the home of Ellen Gould White, co-founder of the Seventh-day Adventist Church, from 1900 to 1915. The form argues that she directed church reorganization, sanitarium and school development, and wrote prolifically here. It judges Elmshaven the best-preserved and most appropriate property reflecting her life, compared with her homes in Battle Creek and Healdsburg.","narrative":"Elmshaven is a three-acre farmstead in the upper Napa Valley, just outside St. Helena, California. Its main building is a two-story redwood farmhouse built in 1885 by Robert Pratt on a stone foundation, with a veranda, stained and etched glass, and later bay windows and a corner tower added in 1902. A four-story tank house and a 1902 office with a library and concrete manuscript vault stand nearby. The property matters because Ellen Gould White, a co-founder of the Seventh-day Adventist Church, lived here from 1900 until her death in 1915. From this home she wrote extensively, promoted Adventist sanitariums and schools, and supported a reorganization of the church's administration. The nomination holds that it best represents her life, since her earlier homes in Battle Creek, Michigan, and Healdsburg, California, were altered or tied to her for a shorter time. The estate once covered 74 acres.","period_of_significance":"1900-1915","architect_builder":"Robert Pratt","architectural_style":"Late Victorian: Stick/Eastlake","criteria":["B"],"status_note":"Current uses are a single dwelling and a museum; the tank house and attached cottage now serve as a residence.
