This paper explores the worldwide unprecedented bunker infrastructure of Switzerland. Since the 1960s, the country has built hundreds of thousands of nuclear bomb shelters in family homes. Drawing on poststructural theories of social practice and ritual theory, the all-pervasive structures in the private sphere are analyzed as transitory spaces that coordinate the movement and connections between different milieus, regimes, and bodies. By studying the operational scripts of the authorities and the spatial arrangements and artifacts of the shelter, the paper argues that a sequenced set of “rites of passage” were to be practiced in order to guarantee a transition into the postapocalypse without any violations of norms, social roles, and affective regimes. However, this “territorializing” process launched by the state with the aim of engineering a “bomb-proof” society met with little success. By ignoring, distorting, or violating the constant prewar situation in their homes, Swiss people, as early as in the 1970s, started to undermine the shelter as an instance of concrete governmentality. Being traversed by various processes of “deterritorialization” the bunker lost its function as a locus of secured passage and transformed into a highly dynamic “empty space” that hides, till this day, residua for creativity and difference.

Debates on risk have largely assumed risk to be the outcome of calculative practices. There is a related assumption that risk objects come only in one form, and that the reason not everything can be transformed into a risk is because of the difficulties in calculating and creating universal quantitative comparisons. In this article, building on recent studies of preparedness that have broadened understandings of risk, we provide an analysis of how preparedness measures might themselves produce risk, in particular through risk’s durable instantiation, or what we call ‘concretisation’. Our empirical focus is on how government agencies in two countries shifted their attention from the risk of nuclear attack during the Cold War to an all hazards approach to preparedness. Comparing the mid- to late-twentieth century histories of the UK and Switzerland, we show that both countries shifted from focusing from a single risk to plural risks. This shift cannot be explained by a change in prevailing calculative practices, or by the fact that the risks changed historically. Instead, it is driven by historically specific changes in how risks are produced and reproduced in relation to how materialisations of risk operate over time.

Recent scholarship has drawn attention to a ubiquitous 20th-century political space that was long overlooked – the bunker. This body of work draws on a variety of theoretical influences and explores multiple historical contexts, yet most remains wedded to the late Paul Virilio's influential 1970s study of the Nazi Atlantic Wall. Enlightening as his 'Bunker Archeology' is, Virilio's theorization has constrained contemporary debates around the function, materiality and temporality of the bunker. Here, we seek to counter this set of limitations in three ways. First, we contest the idea of the bunker as a simple space of human protection and argue for a more expansive conceptual-ization that is attentive to the bunker as a site of extermination. Second, we challenge the assumed concrete materiality of the bunker and suggest an expanded typology, utilizing a range of materials and milieux. Finally, we take to task readings of the bunker as an obsolete relic by highlighting the continued construction, re-appropriation and reimagination of this architectural form.

Current architectural developments tend to find solutions in new designs that neglect historical heritage. The cultural importance of inherited value and the feasible disposition of the safeguarding of existing structures, demonstrate a requirement for sustainable development projects through preservation. Preservation comprises a spectrum of practices that ultimately designate the adaptive reuse of a building or setting, the conservation of its initial state or its reconstruction. The aim of each practice remains the necessity to preserve and showcase environmental, historical and social values through a coherent architectural solution. ​ This thesis looks into the sustainable development through preservation in the derelict island of Sazan. It investigates the quantitative and qualitative potential of interventions in order to preserve inherited values and introduce new activates to complement heritage sites. A preliminary report of historical and environmental data is compiled to determine the values, character, spirit and potential for preservation of the existing built environment. A brief and design proposal is than generated based on earlier findings. ​ The developed framework of research and interventions explores the narrative potential of the derelict sites of Sazan and its classification as historic heritage site, educational prospective and eco tourism destination. It showcases the advantages of preservation as a platform for sustainable developments and the opportunity to achieve continuity of development in formerly abandoned areas.
