"Extraordinary art and architecture installations from around the world. Urban interventions establish strong links between the social and spatial spheres of cities, leading to interactions through which art and architecture make use of public spaces. This book presents a rigorous selection of projects, including installations, events, and art works 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 color, the publication offers a global and comprehensive vision of 21st century cities, as they become meeting places full of creative possibilities."--Publisher’s description
