In Berlin there are more than 2,500 parks, but The New York Times daily calls the Prinzessinnengarten (Park of the Daughters) in Kreuzberg as one of the 10 best tourist destinations in Berlin. In the middle of town, grew 500 vegetables, planted hundreds of volunteer workers, who turned abandoned areas into useful gardens. It's a community project, turning into a tourist attraction.
