Buildings date from the earliest settlement period through the early twentieth century.","why_significant":"The district is argued to be significant at the state level under Criteria A and C for Architecture, Commerce, Exploration/Settlement and Industry. It preserves a concentrated, intact mix of Victorian commercial buildings, waterfront warehouses and large houses built by the lumber economy and its skilled craftsmen. Its isolation and relative lack of modern development pressure helped preserve it.","narrative":"Eureka's Old Town is a 23-block district on Humboldt Bay that grew up around the lumber industry. It contains a Victorian commercial center along Second Street, waterfront warehouses and hotels on First Street, and a residential neighborhood of large houses to the east, anchored by the Carson Mansion. Most buildings are two-story wood structures, with some three- and four-story brick and concrete hotels and offices. Styles range from plain vernacular gable-front buildings and Greek Revival forms to Italianate, Stick, Renaissance Revival and Art Deco designs. Individual properties include early stores built by pioneer Captain H.H. Buhne, saloons, ethnic hotels and a 1911 bank designed by San Francisco architect Albert Pissis. The district was recognized for its architecture and its role in the commerce, industry and settlement of the region between 1858 and 1941. Restoration in the 1970s revived the area for shops, museums and tourism, though parts of First Street have lost many historic buildings to vacant lots and modern construction.","period_of_significance":"1858-1941","architect_builder":"Newsom, Samuel and Joseph; Pissis, Albert; Evans, Knowles","architectural_style":"Greek Revival, Late Victorian, Neoclassical Revival, plus Colonial Revival, Mission Revival, Sullivanesque, Bungalow/Craftsman, Streamlined Moderne, Art Deco and vernacular types","criteria":["A","C"],"status_note":"Largely intact and in active mixed use, with many buildings restored in the 1970s.
