The thesis of this article is that Islamic architecture establishes a clearly recognizable mathematical order and has a special concern for aesthetics. One complements the other. This is exemplified by taking an analytical study and in tracing out certain unknown facts about the design of Fatehpur Sikri, an imperial city built around 1570near Agra in India. A product of creative imagination, it is unquestionably the most ambitious architectural project of the third Mughal Emperor Akbar’s reign and atter the Taj Mahal, the most notable building achievement of the Mughal empire. With Islamic art, so rich, delicate and fragile here, the city is an artistic legacy. Its brief but brilliant story is alive. It evokes in our mind the spell of a historic past and the charm of an exotic legend that piques our imagination. The architecture and spatial planning of Fatehpur Sikri, incredible as it is, carries a message for the contemporary sensitive designers. A search for this message, the springboard of our future accompbshments, is the theme of this article.
