This paper clarifies the particularity in Claude-Nicolas Ledoux’s architectural designs. Like most of the architects in the age of Neo-classicism, Ledoux intends to follow the principle of his age: architecture must express the character suitable for itself, as face conveys emotions. The terms character (caractère) and suitability (convenances), both of which represent the mind of this epoch, concern with surface, exterior, expression and visibility. But in practice, Ledoux transgressed this norm and was accused of producing “monstrous” architecture. His innovation lies in unconscious violation of this legibility and in invalidating the architectural physiognomy.
