From node to network. Knotting process in the modern tradition of postal palaces

Postal palaces represented in the nineteenth and twentieth centuries the occasion of remodeling and developing the city from their nodal essence par excellence. Communication has always played a key role in modern society and, before becoming areal network, it has been embodied by points, for centralities. The study will build on the post offices made since the end of the nineteenth century, questioning the character of monumentality and / or public service given to them, studying the evolution of language in the tradition of Modern. The competition of 1932 in Rome for the construction of four post offices constitutes a turning point in this regard. Examples distant from the rhetoric of regime, and academia, expressive vehicle of rationalism, engines of urban development according to the four cardinal points. The process of specialization and knotting crosses both the scale of the building and the scale of the city and makes it possible to fit the ancient, producing subsequent developments. The study also wants to question on current building code, on the appearance of today's network engaged from communication and its possible morphological evolution.
