The Stillwater Santa Fe Depot is a historic building originally built in March 1900. In 1915, a brick depot was added. The depot was used as a passenger rail station until 1953. The depot was purchased at auction by five Stillwater residents, including three Alpha chapter alumni, in November 1991. Stillwater Station replaced Oklahoma State University's Seretean Center for the Performing Arts as the National Headquarters of the two organizations. The fraternity and sorority share office space, a conference room, and storage space in the converted station, which also hosts the organizations' archives. The brick path leading to the building's entrance has become a "Walk of Fame" with engraved bricks purchased by individuals or chapters.
