Praising Naples beauty is easy: throughout the centuries, numerous influences – Greek, Roman, Byzantine, Norman, Aragonese, Spanish – left their indelible mark on the culture of the city. At the architectural level, Naples is an authentic mosaic of styles and influences, with Renaissance buildings (Palazzo Filomarino), Baroque (San Paolo Maggiore Basilica, Royal Palace) and liberty styles (The theater of San Carlo and Villa Floridiana). What unites many of the city’s museums starting from the 1960s is their harmonic placement within contexts of immense historical and cultural value, with the desire and goal of celebrating the multiple identities of the city. Within the same area, the legacy of the past and the experimentations of the contemporary languages coexist. We chose six museums and identified the institutions that promote a certain type of temporal, formal and conceptual coexistence. They are very different one from the other, but for all of them, art meant a definite transformation of their identity, not only in an architectural sense but also from a social point of view.
