The Iowa Field House is a multi-purpose arena in Iowa City, Iowa. Opened in 1927, it held up to 13,365 people at its height. It was home to the Iowa Hawkeyes men's basketball team before they moved to the newly constructed Carver-Hawkeye Arena in 1983. The building was a regional site for the NCAA Basketball Tournament four times, in 1954, 1956, 1964 and 1966. The pool inside the facility was the home of the Iowa Hawkeyes men's and women's swimming team from its construction through the 2009-2010 season. This pool is believed to be the largest indoor pool in the world at the time of its construction.
