621 17th Street, Commercial skyscraper in Downtown Denver, United States
The 28-story building at 621 17th Street extends 385 feet into the Denver skyline with a modernist architectural design from the 1950s.
Upon its completion in 1957, this structure stood as Denver's tallest building until 1968 when Brooks Towers surpassed its height.
The building appears in the opening credits of the television series Dynasty, displaying the First of Denver logo against the Colorado sky.
The office tower maintains a central position in Denver's business district, providing commercial spaces with direct access to urban transportation networks.
Together with the adjacent 633 17th Street tower built in 1974, the structure forms part of the First of Denver Plaza complex.
