This study aims at showing how C.N.Ledoux applied architecturally the idea of Enlightenment in the Ideal City. Enlightenment of 18th century not only developed neo-classicism in the field of art, but also brought about the changes of ideology and philosophy of the era. C.N.Ledoux, one of the most influential architects of this period, expressed abstractly and symbolically the essential idea of Enlightenment; the skepticism of God's authority, the liberty and equality of man, charity and the willingness of controlling the power of nature, and so on.
