Aria (formerly known as the Lewis Tower Building) is a 33-story Art Deco skyscraper in Center City Philadelphia designed by the firm Edmund Beaman Gilchrist.
An exceptionally slender building, it was one of the city's tallest office high-rises until the skyscraper boom of the late 1980s. It housed offices until 2005 when the building was sold for conversion into condominiums.
The building has undergone extensive interior remodeling and exterior renovation (including facade scrubbing and treatment) and has been renamed Aria, a nod to the building's location just off the Avenue of the Arts, Philadelphia's premier performing arts corridor. The Aria was purchased in 2009 by Richard Oller and Jeffrey Goldstein.
