Wells Fargo Center, Bank tower in downtown Denver, United States

Wells Fargo Center is a 52-story, 698-foot skyscraper at 1700 Lincoln Street in downtown Denver, designed by Philip Johnson under a master plan by I. M. Pei and completed in 1983. Its dark shaft is clad in a dense grid of square windows, and the uppermost floors curve together into a rounded crown, with a curved section bending back along the right edge. A skybridge over Lincoln Street links it to the older Mile High Center at 1700 Broadway.

The building was completed in 1983 by architect Philip Johnson and brought modern design elements to Denver's financial district. Its architecture grew from concepts originally developed for a project in Texas.

Locals call it the Cash Register Building because the curved top floors resemble an antique cash register. The lobby's glass atrium holds an eight-story digital art installation by ESI Design, added in a renovation completed in 2016, along with 14 paintings and 5 sculptures by New York artist Enoc Perez.

The tower stands at 1700 Lincoln Street, and a skybridge over Lincoln Street links it to the older Mile High Center at 1700 Broadway. The lobby was renovated over three years and finished in 2016, when an eight-story digital art installation was added to the glass atrium. It remains a working office building, so upper floors are not open to visitors.

The curved glass crown at the building's top mimics the shape of an antique cash register, a detail that locals have long noticed. This unusual architectural reference is not immediately obvious but becomes a favorite fact for anyone who knows about it.
