DECC Arena It all started at the DECC Arena In the beginning there was only the Duluth Arena Auditorium. While the building itself has been updated since it opened in 1966, the spirit of camaraderie and community has lived on. Today, this space is called the DECC Arena and offers a perfect locale for public exposition shows, the Duluth Figure Skating Club, car shows, hockey practices and conventions.
