H. Winship and designed by architect Luther Turton.","why_significant":"It is a good example of commercial Italianate Victorian architecture and has long been a downtown Napa landmark. It forms a complementary pair with the neighboring Semorile Building, both designed by Luther Turton, whose finest work they represent. Turton was considered the best architect in Napa in the late nineteenth and early twentieth centuries.","narrative":"Standing at the corner of Main and First Streets in downtown Napa, this two-story brick building was erected in 1888 for E. H. Winship, a newcomer from Minneapolis who later became wealthy through a partnership in a local department store. Architect Luther Turton designed it with ground-floor shops and second-floor offices in the commercial Italianate style, with cast iron and plate glass storefronts, bracketed cornice, arched window groupings and a sunburst pediment. A corner octagonal tower, once the tallest structure on Main Street, survived the 1906 earthquake but was removed around 1910. A pharmacy occupied the ground floor for decades, and doctors' offices upstairs gave it the name Hennessey Building; later the Smernes family owned it. It is valued as a downtown landmark, as a fine example of Turton's work, and as a companion to the neighboring Semorile Building, which Turton also designed.","period_of_significance":"1800-1899","architect_builder":"Luther Turton (architect); built for E.
