The Vern Riffe State Office Tower is a 503-foot-tall (153 m) skyscraper in Columbus, Ohio. It was completed in 1988 and has 32 floors. NBBJ designed the building, which is the fifth-tallest in Columbus, and has 102,192 m² of floor area. An earlier idea for this site, also by NBBJ, would have included a site to the west of the present location, and would have effectively closed off South Wall Street north of West State Street. The building was named for Vernal G. Riffe, Jr, who served as Speaker of the Ohio House of Representatives from 1975 to 1994. The complex also contains the 854-seat Capitol Theatre.
