Significance
When built in 1922, the Whiteside Theatre was the second grandest movie palace in Oregon at that time. The building is an excellent example of Italian Renaissance architecture applied to a theatre. It is probably Corvallis' best historic commercial building in terms of original design and integrity. The upper story of the exterior of the building retains its original ornamented effect, executed in brick, glass, cast "stone" and plaster. The original layout of the theatre is intact and numerous interior decorative features remain from the 192O's period.
