The Barnes Foundation has hit its $150 million fundraising target, and now has enough money to complete its controversial move to Center City Philadelphia. But the foundation isn’t stopping there, announcing an extension of the campaign, and a new target of $200 million, to be raised from “national and international” donors. The extended campaign may be due in part to rising construction costs – the Barnes’s proposed $100 million facility is likely to end up with cost overruns, and the museum wants to be prepared.
