Simeon Bruner talks about the building of the Mass MoCA Museum by transforming the old mill buildings. Mass MoCA is the largest center for contemporary art in the United States. It opened to national acclaim in 1999. Twelve years of master planning and design went into the museum’s creation; its changing exhibits continue to attract over 125,000 visitors per year. A young museum, with no permanent collection and no endowment, commercial rental space is its de facto endowment. Reshaping an old industrial complex and former brownfield site, the museum is central to the economic revival of North Adams MA.
