The Massachusetts Museum of Contemporary Art (MASS MoCA) is a museum in a converted Arnold Print Works factory building complex located in North Adams, Massachusetts. It is one of the largest centers for contemporary visual art and performing arts in the United States.
MASS MoCA originally opened with 19 galleries and 100,000 sq ft (9,300 m2) of exhibition space in 1999. It has expanded since, including the 2008 expansion of Building 7 and the May 2017 addition of roughly 130,000 square feet when Building 6 was opened.
