Many churches, cathedrals, castles and lodgings, whose relevance and the quintessence of knowledge reservable by these predecessors, cause a questioning with the trivialization of current computers, be the subject of a new look . In the following we demonstrate: (i) The "Yakam Matrix" in ancient architecture, (ii) indicators of 21st century computer-aided architecture and (iii) numerical simulation and perspective of the developing architecture sustainable.
