University of Denver Arena was a 5,200-seat multi-purpose arena in Denver, Colorado. It was home to the University of Denver Pioneers ice hockey team. It also hosted several Frozen Fours. It was razed in 1997 to make room for the $75 million Magness Arena, which opened in 1999. The structure was originally a U.S. Navy drill hall in northern Idaho, built in the early 1940s at Farragut Naval Training Station at Lake Pend Oreille.
