The USM Field House opened in May 1998 to complete the Costello Sports Complex facility. It features a six-lane, 200-meter track with tennis courts, basketball courts as well as practice areas for baseball and softball.
USM's men's and women's track and field teams compete in the field house. The Field House has ben the site of numerous Little East Conference Championships as well as the NEICAAA Women's Championships (2000) and the New England Division III Women's Championships (2010) since the facility opened. The Maine State Principals Association has also staged one of its annual high school state championship meets at the Field House.
In addition, USM's men's and women's tennis teams use the facility for practice and for competition when weather dictates. The Field House seats 750.
In addition to academic year activities, the Field House is also an integral part of the USM Summer Sports Camps program and a number of sports clinics held throughout the year. It is also one of the university's fitness facilities with opportunities for running and walking for exercise.
The Field House is also a frequent venue for community events such as high school track meets, scholastic fairs and commercial shows.
