- This article is about the 1989, 32-story building. For the 1976, 18-story building, see Regions Plaza.
The Regions-Harbert Plaza is a 437 foot tall, 32 story office tower, with adjoining 2-story retail, located at 1901 6th Avenue North, between 19th Street North and 20th Street North. The building, with a total of 613,764 square feet of rentable floor area, includes office, retail, restaurant, and banking space. The building was originally known as the AmSouth-Harbert Plaza and was renamed in July 2007 when AmSouth merged with Regions.
Completed in September 1989, the postmodern-style skyscraper was designed by Hellmuth, Obata & Kassabaum of St Louis with Brasfield & Gorrie serving as the general contractor. The tower was constructed atop a large downtown site that once was occupied in part by both the Temple Theatre and the Downtown YMCA (1911).
 Architectural Design
The brown granite cladding stretches from its base to the copper-roofed, pyramid-shaped penthouse. The shape of the roof was inspired by the towers of the nearby 1st Methodist Church and Cathedral Church of the Advent. The famous "balls" at the corners of the tower mirror those on the corners of the Advent's tower, and the color of the granite was selected to blend with the colors of that church, which sits directly across 20th Street. The Harbert Center on 4th Avenue North was built at the same time and has a similar style of detailing.

 Additional Information
The original anchor for the retail center at AmSouth-Harbert Plaza was a 21,500 square-foot Parisian department store, which relocated from its former downtown flagship on 2nd Avenue North. The store converted to a Belk in 2005. In late July 2008 Belk announced that they would close the location in January 2009. The space was leased for an Adeptio Wellness Center in September 2010.
