Gammage Memorial Auditorium

ASU Gammage (formerly known as Grady Gammage Memorial Auditorium) is a multipurpose performing arts center at 1200 South Forest Avenue at East Apache Boulevard in Tempe, Arizona, within the main campus of Arizona State University (ASU). The auditorium, which bears the name of former ASU President Grady Gammage, is considered to be one of the last public commissions of American architect Frank Lloyd Wright. It was built from 1962 to 1964.

ASU Gammage stands as one of the largest exhibitors of performing arts among university venues in the world, featuring a wide range of genres and events.

ASU Gammage was listed on the National Register of Historic Places in 1985.

History
The process that led to construction of the auditorium began in 1957 when incumbent university President Grady Gammage desired a unique facility for the ASU campus. In 1956, a collapsed roof rendered the school’s combination auditorium/gymnasium unusable. Gammage recruited his friend Frank Lloyd Wright to design the new building. He would, with various budget related alterations, base its design on a circular opera house that he had conceptualized for the city of Baghdad sometime prior upon the invitation of Iraqi King Faisal II. Plans for that opera house were abandoned after Faisal’s assassination in the 14 July Revolution. Wright is also said to be responsible for siting the auditorium, selecting an athletic field at 1200 South Forest Avenue which had formerly held on-campus G.I. housing units.

Wright and Gammage both died in 1959, leaving Wright's protégé William Wesley Peters to undertake completion of the auditorium. Spearheaded by the Robert E. McKee Company, construction of the facility commenced in 1962 and was completed twenty-five months later, officially opening on September 18, 1964, in time to host The Philadelphia Orchestra conducted by Eugene Ormandy.

The auditorium was used for the funeral of Arizona Senator and 1964 Republican presidential nominee Barry Goldwater on June 3, 1998.

On October 13, 2004, the auditorium was the site of the third and closing debate between George W. Bush and John Kerry in the 2004 U.S. Presidential Election.

Structure
The structure measures 300 ft long by 250 ft wide by 80 ft high. Fifty concrete columns support the round roof with its pattern of interlocking circles. Twin "flying buttress" pedestrian ramps extending 200 ft from the north and east sides of the structure connect the building to the parking lot. The auditorium seats 3,017 people on its main floor, grand tier and balcony. The stage can be adapted for opera, theatricals, musicals, concerts, and lectures.
