This thesis examines the reactivation of the abandoned settlement of Asfontylitis on Amorgos through an architectural approach that views abandonment not merely as the loss of the built environment, but also as the disruption of a broader social and cultural system. Intimately linked to agricultural production, seasonal habitation, traditional techniques, and collective practices, Asfontylitis preserves the material vestiges of that way of life to this day: stone structures, courtyards, threshing floors, wells, dry-stone walls, and traditional pathways.
 Research based on on-site observation and discussions with individuals who knew the settlement during its active period highlighted the importance of cooperation, interdependence, and the shared use of resources as fundamental characteristics of life there in the past. Consequently, reactivation cannot be limited to conventional restoration; it must also restore the relationships, knowledge, and practices that gave the place its meaning.
 The central idea of the proposal is to transform Asfontylitis into a continuous cultural workshop, where new forms of habitation are linked to work, learning, production, and collective action. Existing structures are repurposed, courtyards and threshing floors take on new collective functions, wells are reactivated as hubs for gathering and knowledge-sharing, and traditional paths reconnect the site into a unified network. The program is structured around artistic, traditional, and agricultural workshops, aiming to transmit and preserve local intangible heritage throughout the year.
 The architectural proposal is grounded in the principles of minimal intervention, adaptive reuse, and participatory construction. Existing structures are preserved and repaired using local materials and traditional techniques, while new, lightweight, low-tech structures are introduced in a distinct and reversible manner. The construction process itself is integral to the project, as collective labor serves as a tool for education, knowledge transfer, and reconnecting with the place.
 Thus, “WHAT RE-MAINS” proposes not a static representation of the past, but an evolving process of re-inhabitation. The project views architecture as a framework that enables an abandoned site to transform once again into a space for collective life, production, and cultural continuity.
