The Boeing United Airlines Terminal, Hangar and Fountain in Cheyenne, Wyoming were built for Boeing Air Transport between 1929 and 1934. The Louis Sullivan-influenced designs form a consistent theme in a time when Cheyenne Municipal Airport was a major air transport facility. The 1930 hangar was designed by Cheyenne architect Frederic Porter, Sr. The 1934 Art Deco fountain was designed as a memorial to early aviation history.
