The Massachusetts-based DeCordova Museum is going ahead with plans for an ambitious $10 million expansion and renovation. The plans include a sculpture ‘zoo,’ a new visitors’ center, and loads of behind-the-scenes improvements designed to better protect and house the museum’s collection. The fund-raising will be a challenge, but the museum’s director insists that “ten million dollars is not really a lot of money,” and with no signs of imminent economic recovery nationally, the DeCordova’s decision underlines a feeling by many arts groups that forward progress can no longer be put on hold simply because conditions are less than perfect.
