Janssen and Co. and later used as the Humboldt Cultural Center.","why_significant":"The nomination presents it as a well-preserved 1875 mercantile building with a cast iron front shipped from San Francisco. It housed the first elevator installed in Eureka, and its water-powered equipment still remains. It is also tied to Hans Henry Buhne, who ran it as a ship's chandlery, and it survives as a reminder of North Coast early days.","narrative":"Built in 1875 at 422 First Street in Eureka, this two-story brick loft building was planned as the mercantile center of the North Coast. It measures 34 by 110 feet and has a flat roof, wood-frame floors, interior wood columns and a street front of cast iron and glass. The iron columns carry the mark of the San Francisco Iron Works, 1875. Inside, the building held Eureka's first elevator, a water-powered unit that remained the only one in the northern part of the state for many years, and its equipment still survives along with long classical-style shelving. In 1889 Hans Henry Buhne, an early Humboldt Bay settler and business leader, took over the building and business and turned it into a ship's chandlery supplying Eureka-based coastal vessels. A later mezzanine with turned spindles gives the main room a ship-like feel. After a vacancy, the building was rehabilitated, its iron front restored, and it was slated to serve as an art and cultural center.","period_of_significance":"19th Century (constructed 1875)","architect_builder":null,"architectural_style":"California Gold Rush style or California Renaissance","criteria":[],"status_note":"Described as in excellent condition.
