Significance: Currigan Exhibition Hall long stood as one of Denver’s precedent-setting works of modern architecture. Upon completion in 1969, Currigan boasted 100,000 square feet of column-free exhibition space and was the world’s largest rigid space frame. The building became one of the largest uses of weathering steel (CorTen) in a public building. It received worldwide recognition as the prototype for exhibition halls and airline hangars. To make way for the expansion of Denver’s convention center, the hall’s demolition was completed in 2002, even though sections of the building could have been individually disassembled and moved.
