Nestled within the voids of Naples’ Fontanelle Cave, this project proposes a funeral home and crematorium that emerges from geological irregularities rather than imposing upon them. Drawing from Yeoryia Manolopoulou’s Architecture of Chance, the design embraces erosion, decay, and adaptation, treating architecture as an evolving presence. Through metal, stone, and clay, it negotiates permanence and transformation in response to the shifting nature of Neapolitan yellow tuff. Spaces form through cycles of subtraction and accretion, revealing rituals of passage through temperature, texture, and light. Heat seeps into the porous stone, and shafts of filtered light choreograph the mourners’ path, allowing the architecture to transform, adapt, and erode in dialogue with the cave. It becomes both a vessel for memory and a material record of time’s erosion.
