MassMutual Center

The MassMutual Center is a multi-purpose arena and convention center complex located in downtown Springfield, Massachusetts, United States, in the city's Metro Center. The arena opened in 1972 and the convention center opened in 2005. It serves as a venue for meetings, conventions, exhibitions, sporting and entertainment events.

Previously owned and operated by the City of Springfield and various management groups until 1997, the city transferred ownership of the facility to the Massachusetts Legislature. Shortly after, ownership was given to the Massachusetts Convention Center Authority who in turn began working on plans to renovate and expand the facility. The two-year project, which began in 2003, included renovations to the 8,000-seat arena and the addition of a convention center. Its unique design allows for 3 to 4 concurrent events or one large event.
