It is the largest curling venue in the United States, and has hosted two World Championships, the US Olympic Trials, and numerous National events.

Paulucci Hall, located beneath the lobby and built with the original Duluth Arena Auditorium in 1966, hosts numerous events.

In the mid-1990s a $30 million convention center was added, which is the site of numerous social, business and entertainment events, and features the 26,000 sq ft (2,400 m2) Lake Superior Ballroom, the 12,000 sq ft (1,100 m2) Harborside Ballroom, and 25 Meeting Rooms.

The expansion project also included a new parking ramp and more space for conventions and concerts, which DECC director Dan Russell said will bring more events to the complex.

Construction began in September (2008), and the AMSOIL Arena opened on December 30, 2010 for a Men's UMD hockey game against the University of North Dakota.
