Divisions Elmshaven is a historic house museum at 125 Glass Mountain Lane in St. Helena, California, United States.

[2] Elmshaven is located in a rural-residential area north of downtown St. Helena, on the east side of Glass Mountain Lane.

The main house is a two-story frame structure built of redwood and finished in shiplap siding.

Stylistically it is a vernacular expression of Victorian architecture, with a square turret at the right front corner, capped by a pyramidal roof.

Ellen White purchased the home in 1900, naming it "Elmshaven" after the row of elm trees at its front.
