Built in 1904, the Carnegie Library, Main Branch, was the first true library structure in the city, occupying an entire block at the east end of Browne’s Addition. Philanthropist Andrew Carnegie funded construction of the building, and acclaimed Spokane architectural firm Preusse and Zittel designed the structure. The building is an excellent example of neo-classical styling, exhibiting several unique and well-preserved features. After a period of vacancy, Integrus Architects of Spokane renovated the building in the 1990s to serve as the firm’s primary office building.
