Completed 1957, seated 6,000. Noted for its unusual construction: the building site was mounded with earth, the mound covered with cement to form a dome, then the earth was excavated out from beneath. Served as a public auditorium until demolished in 1987. The Auditorium was located between downtown Albuquerque and I-25, on Grand Avenue. Performers at the Auditorium included Victor Borge, Frank Sinatra, and Bob Hope (who compared the design to a flying saucer and asked when it was leaving for the moon).
