The Gowan Company Building, formerly known as the Yuma Main Post Office or Yuma Downtown Postal Annex, is a historic building in Yuma, Arizona. Constructed in 1933 to serve as the city's main post office, the building's design, a work of architect Roy Place, is a blend of the Beaux Arts and Spanish Colonial Revival styles. The design includes a loggia supported by Corinthian columns, wrought iron railings and window bars, a molded belt course between the building's two stories, a projecting bracketedcornice, and a red tile roof. The post office was built toward the end of the Beaux-Arts phase of federal building design, as government architects shifted to a "starved classicism" style in the ensuing years.[2]
The building was added to the National Register of Historic Places on December 3, 1985 as the U.S. Post Office—Yuma Main.[1] It was purchased by the Gowan Company in 1996 for preservation and use as its headquarters.
