Groen erfgoed in de stad shows how nature-rich places in cities came into being and what they contribute to the city’s identity. From the medieval beguinage to a Post 65 roof garden. How functional allotments and cemeteries are transforming into biodiverse oases. Preserving green heritage is a challenge. Intensive use, new development and climate adaptation force difficult choices. How can the knowledge and ideas of the past provide inspiration for the green city of the future?
