An ancient territorial axis along which a part of the city has been structured. By virtue of its rank, this road will continue to play an ordering role within the city, i.e. the role of a modern armour, becoming the testimony of large complexes and spaces that, since the mid-19th century, have articulated the expanding city and given shape to its new needs: a psychiatric hospital, a cemetery, factories, a shopping centre, an amusement park. These places reject the logic of urban homogeneity, imposing themselves as coherent, autonomous realities. Some authors call these (separate and differently regulated) places ‘heterotopies’.
