The heritage of the Phlegraean Fields comprises a multitude of sites whose blurred boundaries blend firstly with the natural landscape, from which they emerge and derive their particular morphological configurations, and secondly with the anthropised landscape layered, over the centuries, on top of these millenary memory places. The topic of collective memory thus becomes the basis for a specific reflection on issues concerning collective heritage, where individual memory is constructed by participating in communicative processes. The obstinate presence of the ruins, testifying to their eternity and their victory over the irredeemable passing of time, therefore reveals its entirety in one of the largest and most remarkably articulated archaeological complexes within the archaeological park of the Phlegraean Fields, i.e. the Thermae of Baia, whose monumental domes undoubtedly constitute an archetype for the Roman to build such ambitious opus caementicium structures.
