One Nationwide Plaza is a 40-story skyscraper in Columbus, Ohio, United States, that serves as the corporate office headquarters of Nationwide Mutual Insurance Company. It is part of the complex of buildings known as Nationwide Plaza.

Nationwide outgrew its 246 North High Street Building by the 1970s and work began on a new headquarters for the company. In 1977, the {{cvt|485|ft|m|adj=mid|-tall}} building was completed. The building is located at the corner of N. High Street and what is now Nationwide Blvd. on the northern edge of downtown Columbus, Ohio.

Design

The building was designed by Brubaker/Brandt (the same firm that designed Rhodes State Office Tower, the tallest building in Columbus) and Harrison & Abramovitz.{{cite web|url=http://www.emporis.com/application/?nav=building&id=1nationwideplaza-columbus-oh-usa |archive-url=https://archive.today/20130215222338/http://www.emporis.com/application/?nav=building&id=1nationwideplaza-columbus-oh-usa |url-status=usurped |archive-date=February 15, 2013 |title=One Nationwide Plaza, Columbus | 119120 |publisher=Emporis |date= |accessdate=2022-05-03}} The façade is dark vertical steel ribs bordered by white limestone ends which follows the modernist style. Blue spotlights light the exterior at night in the same color of Nationwide's logo. In December the interior lights are set so that it reads "happy holidays" to observers of the building, with thematic messages similarly displayed during other holidays and special events such as Columbus Blue Jackets and Ohio State Buckeyes victories and accomplishments.

There was once a restaurant on the 38th floor called One Nation, which opened in November 1977. The glass elevator on the side of the building is an express elevator that was designated for customers going to the restaurant. One Nation closed in 1997 after '[failing] to come to terms with the building's owner'.{{Cite web |author=Staff Writer |title=One Nation -- Columbus' restaurant in the sky |url=https://www.dispatch.com/story/news/2010/06/18/one-nation-columbus-restaurant-in/23354993007/ |access-date=2023-01-28 |website=The Columbus Dispatch |language=en-US}} The glass elevator is no longer in service.
