633 17th Street

633 17th Street is a 32-story office tower in Denver's financial district with a clean, modern exterior design. The building rises approximately 434 feet (132 meters) and contains office space for multiple companies and organizations.

The tower opened in 1974 as First Interstate Tower North and was the tallest building in Denver at that time. Within four years, another structure surpassed it in height, reflecting the city's rapid development.

The tower became a symbol of Denver's economic growth and modernization during the 1970s when the city was expanding rapidly. It represents how the downtown area transformed into a major business center during that era.

The tower is centrally located in the financial district and is easily accessible by public transportation from downtown Denver. Since it is a private office building, access to interior spaces may be limited or restricted during business hours.

The building appeared in the opening credits of the television series Dynasty, making it recognizable to viewers worldwide. This television feature introduced it to a much larger audience than typical office buildings normally reach.
