Pythian Castle
Why it's listed
Pythian Castle is a two-story wood building on a corner two blocks north of Arcata's Plaza, completed in April 1885 for the Knights of Pythias North Star Lodge No. 39. Contractor A. P. Glidden of Eureka built it. Its Queen Anne design is defined by five projecting towers: three round-corner towers with conical roofs and two square bays at the centers of the street-side walls, along with curved brackets, colonettes, and pediments. The lodge used the spacious upper hall for ceremonies and meetings, while the ground floor housed shops, a kitchen, and a dining room. Over the years it also served as a kindergarten, temporary high school space, and physicians' offices. The Fraternal Order of Eagles bought it in 1945. A restoration beginning in 1984 corrected 1950s exterior alterations and converted the interior to apartments and commercial space. It was listed as Arcata's finest surviving Victorian commercial building and an example of Queen Anne design.
Significance in brief: The nomination argues it is an excellent example of commercial Queen Anne architecture, with five towers, bays and applied ornamentation. It is described as Arcata's only remaining Victorian commercial building that has kept its architectural and historic character. It is also important for its long role in the community's social and commercial life, with lodge activities upstairs and businesses below.
