It was Eureka's largest and finest lodge hall and housed a leading merchandising store, serving as both a commercial centre and a meeting and social hall. Reviewers accepted it for its architectural and social significance despite first-floor alterations.","narrative":"Built in 1883, this two-story brick building at 123 F Street in Eureka was designed as the lodge hall of the Independent Order of Odd Fellows. James Simpson, a well-known local builder, constructed it. It measures 40 by 110 feet and has unreinforced brick bearing walls, arched windows with keystones, cast iron pilasters, and two Ionic columns supporting a balcony beneath a tall entrance pavilion. An ornate cornice carries a high plaster mansard roof with iron grillwork. The upper floors remain largely original, while the ground floor was altered in 1920 with new windows and a relocated corner entrance. The second floor served as Eureka's largest and finest meeting hall for service and community groups, and its dedication drew the largest gathering in the city's history. The ground floor held the H. Barman store and a county tax collector's office. It is regarded as Eureka's finest Second Empire building.","period_of_significance":"1800-1899","architect_builder":"James Simpson","architectural_style":"French Empire / Second Empire (mansard)","criteria":[],"status_note":"Upper floors largely unchanged; first floor altered in 1920.
