The PNC Building, officially One Cascade Plaza, is a 23-story high-rise structure in Downtown Akron, Ohio.

The building is the second-tallest in Akron.

It was owned by the National City Bank until 2008, when the Pittsburgh-based PNC Bank purchased the company.

In 2016, after years of the bank only having street-level signage outside the structure, PNC opted to install skyline signage on all four sides of the structure.
