This book provides a cross-urban account on murals, street art, and public art in cities around the globe. It reviews the rules, policies and regulations that frame how murals and street art are managed across a range of cities and contexts. Murals and street art serve as dynamic stages for communities and individuals with multiple and sometimes opposing identities, with the potential to cause disturbance and conflict. The book investigates the challenges they present to cities and city administrations, and the policies and practices that are crafted to address them. The global landscape of today's mural policies is discussed comparatively across a range of cities, and the impact of written rules, unofficial practices, and institutional arrangements on city spaces, walls, and surfaces is examined. An important contribution to this growing field, the book will appeal to students, practitioners, and scholars with an interest in public art, municipal governance, public space management, cultural policy, and urban design.
