The address was later corrected to 1091 Larkmead Lane, Calistoga.","why_significant":"The winery reflects a significant period in Napa County's wine industry: a shift in construction techniques, an expanding eastern market for California wines aided by rail, and the influence of Italian and Swiss-Italian settlers in stonemasonry and viticulture. Its square plan and flat-site gravity-flow design are uncommon. The original stone building remains essentially unchanged since 1906-07.","narrative":"Larkmead Winery is a two-story stone winery on the floor of the Napa Valley, built in 1906-07 for Felix Salmina & Co. beside the Southern Pacific Railroad. Local carpenter Wilbur A. Harrison designed it, and the stonemasons of G. Brovelli & Co. of St. Helena built it from locally quarried stone. Its 66-foot square plan and gravity-flow layout on flat ground were unusual among early California wineries, and the railroad access appears to have outweighed the lack of a hillside. The stone building replaced an earlier frame winery from about 1884. Its rail shipments to eastern markets, its Italian and Swiss-Italian stonemasonry and its craftsman builder all illustrate a significant period in Napa County winemaking. Additions followed in 1911, the 1930s and 1976 as production grew, but the original stone structure remains largely unaltered. The winery survived Prohibition and has operated as a champagne cellar since 1958, still surrounded by vineyards.","period_of_significance":"1900- (specific dates 3/1906-2/1907)","architect_builder":"Wilbur A.
