This study describes an alternative reality: the establishment of an architectural multidimensional retrospection. The projects are the result of a fundamental conflict, which is the articulation and the programmatic of a specific generic “volume” in its two most important stages: the “original” structure and the present one, result of centuries of transformation. Milano is the arena for experimentation, the purpose is the clash of the contemporary city and the MEDIOLANUM, and the method is based on the regeneration of the specific buildings of the Roman City inside the actual context through the confrontation of the original structures inside the modern reality.
