In 2005, Boston University opened Agganis Arena for Hockey and Basketball. The facility was designed as a hockey arena: a departure from BU’s Walter Brown Arena which had the smallest playing ice in Division I. Agganis Arena seats six to seven thousand, and also serves the city of Boston as a mid-size venue for popular events that could not fill the 18,624 seat TD Garden (previously the Fleet Center). The arena is named after Harry Agganis, “The Golden Greek,” BU alumnus, Terrier sports star, Boston Red Sox first baseman, and Boston native who died of a pulmonary embolism in 1955 at the age of 26.
