can be found on many Purdue logos and those of the cities of Lafayette and West Lafayette. Southwest of the Stadium Mall is the Edward C. Elliott Hall of Music, one of the largest proscenium theaters in the world. Elliott Hall of Music serves as the home of the Purdue "All-American" Marching Band, Purdue Bands and Orchestras, the WBAA studio. Purdue's Student Concert Committee often invites famous entertainers to perform there for an audience of students, faculty, and the public. West of the Elliott Hall of Music is the Armory Building. The Armory Building was rebuilt in 1918 after a fire and houses the university's ROTC programs and other clubs. In March 2019, university president Mitch Daniels described a proposal to repurpose the Armory Building, suggesting the space may be used for residential dining, retail, or classrooms but later said no changes would be made. Memorial Mall The Purdue Memorial Mall, south of the Purdue Mall, is the original section of campus. A popular meeting place for students, the grassy, open Memorial Mall is surrounded by the Stewart Center, Wetherill Laboratory of Chemistry, Stanley Coulter Hall, the Class of 1950 Lecture Hall, the Recitation Building, University Hall, and Stone Hall. The Memorial Mall also features the Hello Walk. Near this section of campus is Felix Haas Hall, which was constructed in 1909 as Memorial Gymnasium in memory of the 17 Purdue University football players, coaches, alumni, and fans who perished in the Purdue Wreck railroad accident on October 31, 1903. The structure was renovated in 1985 to house the Computer Science department. In 2006, it was renamed in honor of retired Provost Felix Haas and began to also house the Statistics department. East of the Memorial Mall is the Purdue Memorial Union, Purdue's student union building, and the adjacent Union Club Hotel. University Hall is the only building remaining from the original six-building campus. Construction began in 1871, when the building was known as "The Main Building". The building was dedicated in 1877 and the project cost $35,000 to complete. University Hall originally housed the office of the president, a chapel, and classrooms, but was remodeled in 1961 to house only the department of history and classrooms used by the School of Liberal Arts. At the request of John Purdue, he was buried in the Memorial Mall, directly across from the main entrance of University Hall. South Campus The area
