From the National Register application on the Building:

"Constructed in 1926 and 1927, the Russellville Masonic Temple is a Classical Revival style building located at the 200 block of South Commerce Avenue in Russellville, Arkansas. The Russellville Lodge No. 274 began construction of the building in 1926 and it was finished in 1927. The brick masonry building rests upon a continuous concrete foundation and is topped by a flat roof. The building is fairly unornate with the exception of the Classical temple facade. The temple facade projects forward toward South Commerce A venue and features large Doric columns recessed into the building's entryway. The building's original windows were replaced with smaller single-pane stationary windows in the early 1970s. In 2004, through a grant from the Arkansas Historic Preservation Program, all windows on the front facade of the building (9 total) were restored to their original configuration with operable double casement wood windows."
