Its greatest significance is said to lie in the place Charles Krug holds in the viticulture and winemaking of California and of Napa Valley. It is also noted for the unusual architectural detailing of the stable building.","narrative":"Charles Krug Winery near St. Helena in Napa County, California, includes a two-story plastered stone winery built in 1874 and a large stable, now an aging cellar, built in 1881. Krug founded the operation in 1861, and a section of the original cellar's south wall, which survived an 1874 fire, was incorporated into the rebuilt winery. The winery has arched windows and doors, rusticated wall angles, a corrugated metal roof with dormers and a wooden octagonal cupola. The stable has a ventilation level of wood with a double arched roof, wooden hemispheres, and acorn-shaped details. Krug, born in Germany in 1825, made the first wine in Napa County in 1858 and became a leading figure in early California viticulture, serving as an officer in state and local wine societies. The property is described as the oldest operating winery in Napa Valley and is a California Historical Landmark. It remains in use and open to visitors.","period_of_significance":"19th and 20th Century (boxes checked; no specific dates given)","architect_builder":"Charles Krug (builder of the winery and stable)","architectural_style":null,"criteria":[],"status_note":"Condition marked fair; exteriors stated as not substantially altered since construction.
