Nella definizione di Ungers della città come coincidentia oppositorum si ritrova un’immagine chiara della sua natura persistente. Klose proponeva di trattare le diverse parti della città secondo principi modernisti, separando razionalmente le funzioni e privilegiando igiene ed efficienza, organizzando lo spazio attraverso ritmi astratti e ripetitivi, privi di dialogo con il passato, dal quale la città storica traeva il proprio ordine complesso e la densità dei significati. La dimensione sociale che sostiene la vita urbana è stata in gran parte erosa nella seconda metà del Novecento dalla motorizzazione di massa, che ha ridisegnato la città secondo la logica del traffico e della mobilità. A partire da queste premesse, la tesi indaga l’infrastruttura delle circonvallazioni di Milano, oggi tra gli spazi più dominati dal traffico. Questi vuoti urbani tracciano la crescita della città come gli anelli di un tronco, segnando limiti ormai superati e oggi definiti quasi esclusivamente dalla logica dell’automobile. Sebbene appaiano come elementi di separazione, le circonvallazioni possono essere reinterpretate come dispositivi di connessione, capaci di mettere in relazione parti della città non più leggibili semplicemente come “interno” ed “esterno”. Attraverso un’analisi morfologica e storica, la prima circonvallazione rivela la permanenza delle antiche mura spagnole, il cui volume sopravvive oggi come una fascia edilizia che si ispessisce al centro dell’infrastruttura. Questa eredità dimostra che tali sistemi non sono solo dispositivi tecnici, ma luoghi in cui si sono stratificati forme, funzioni e identità. Questa osservazione guida la riflessione sulla seconda circonvallazione, il cui spazio centrale è privo di un ruolo definito e oscilla tra due configurazioni: corsia preferenziale per il trasporto pubblico e i taxi, oppure piattaforma per parcheggi temporanei e mercati locali. All’interno di questa ambiguità, il progetto interpreta l’infrastruttura non secondo una logica funzionalista, ma come dispositivo capace di generare urbanità. Un luogo marginale e privo di identità viene ridefinito attraverso funzioni collettive e attività capaci di sostenerne la presenza nel tessuto urbano. Situato tra le principali direttrici del traffico e la vita quotidiana, il progetto ne valorizza la duplice natura di spazio di transizione e di destinazione, trasformando un territorio sottoutilizzato in un nuovo luogo per la città.

Abstract
In Ungers’ definition of the city as coincidentia oppositorum, we find a clear image of the city’s enduring nature. Klose proposed addressing urban areas through modernist principles, rationally separating functions and prioritizing hygiene and efficiency, organizing space through abstract and repetitive rhythms detached from the past—a past from which the historic city derived its complex order and density of meanings. The social dimension underpinning urban life was largely eroded in the second half of the twentieth century by mass motorization, which reshaped cities according to the logic of traffic and mobility. Building on these premises, this thesis investigates the infrastructure of Milan’s ring roads, today among the most traffic-dominated spaces in the city. These urban voids trace Milan’s growth like tree rings, marking former limits that the city has now surpassed and that are shaped almost exclusively by the logic of the car. Although ring roads appear as boundaries and elements of separation, they can instead be reinterpreted as devices of connection, capable of linking urban parts no longer readable simply as “inside” and “outside.” Through morphological and historical analysis, the first ring road reveals the persistence of the ancient Spanish walls, whose former mass survives as a strip of buildings thickening at the center of the infrastructure. This legacy shows that such systems are not merely technical devices, but places where forms, functions, and identities have accumulated over time. This observation informs a reflection on the second ring road, whose central strip lacks a defined role and oscillates between two configurations: a priority lane for public transport and taxis, or a platform for temporary parking and local markets. Within this ambiguity, the project interprets infrastructure not through functionalist logic, but as a device capable of generating urbanity. A marginal and identity-less site is redefined through collective and income-generating functions, strengthening its role within the urban fabric. Located between major traffic routes and everyday life, the project embraces its dual nature as both arrival point and transition space, transforming an underused territory into a new place for the city.| File | Dimensione | Formato | |
