The article looks at the development of the concept of art in public space by rereading a few critical texts. Since the publication in 1995 of the book Mapping the Terrain. New Genre Public Art edited by Suzanne Lacy, Public Art has aroused interest in the practice and theory of various authors and it has been redefined over the years. What has emerged is a progressive movement towards the issues of politics and society, as occurred with New Genre Public Art (Ngpa), interpreted in terms of a reaction to the consensus policies practiced on a large scale in urban redevelopment programmes. The Ngpa’s starting stance is the result of a decision to support minorities, in order to represent and defend a pluralist society.
