Urban interventions establish strong links between the social and spatial spheres of cities, giving place to interactions by which art and architecture make use of public spaces. Urban Interventions presents a rigorous selection of projects that have transformed streets, parks and derelict areas of cities all over the world into extraordinary public spaces, seeking people’s involvement through a wide variety of interactive and collaborative activities. Fully illustrated in colour, the book includes installations, events and art works and offers a global and comprehensive vision of 21st century cities, as they become meeting places full of creative possibilities.
