Considered to be the last public commission of architect Frank Lloyd Wright the Grady Gammage Memorial Auditorium is on the campus of Arizona State University in Tempe, AZ. The structure, which was named after the ASU president from 1933-1959, measures 300 feet long by 250 feet wide and is 80 feet high. Fifty concrete columns support the round roof with its pattern of interlocking circles.
Pictured in the bottom photo is one of the twin “flying buttress” pedestrian ramps which extend 200 feet from the north and east sides of the auditorium and connect the building to the parking lot.
