The USM Field House opened in May of 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. Men's and Women's Indoor Track and Field Teams compete in the Field House. In addition, both tennis teams use the facility for practice and for competition when Maine's 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.

The facility was built by Harriman Associates and cost $5.5 million.
