Construction began in 1912, and the cornerstone was laid on November 28, 1912.[8] It was dedicated in 1915, making it the first building on campus.[5][8][9] The site chosen for Dallas Hall is one of the highest points in Dallas County.[6] It stood alone on a flat prairie.[8] This, and the building's monumental size, is the origin of SMU's nickname, "The Hilltop".[9][6] Constructed of brick, it is three stories tall.[3] The building was oriented so that the crest of the building perfectly aligned with the Praetorian Building, then the tallest building in Dallas.[6]
Upon its opening, all of the university's facilities, except for female dorms and temporary housing for some male students, were housed in Dallas Hall.[6] It housed all classrooms for a decade after opening.[7] Over the years, it has been home to classrooms, offices, a chapel, a hamburger grill, a post office and a barbershop.[5][8] A highly symmetrical campus has since been constructed around Dallas Hall.[6] It celebrated its 100th anniversary on November 12, 2012, with a dinner for university administrators and donors.[8] It has been listed on the National Register of Historic Places since November 17, 1978.[7]
Dallas Hall is used for SMU's convocations and graduations.[8]
