How do you create a radically open platform for building new cultural capital in cities? That's been the job of Leslie Koch, president of the Trust for Governors Island, a nonprofit organization created by the city of New York to run what is an historic former military base being transformed into a park by and for New Yorkers. With the lightest possible touch, she has transformed a set of empty buildings and grounds into a platform animated by artists, collectors, and passionate hobbyists. It's a model every city can learn from. Email me via: Coletta (at) knightfoundation.org.
