"The Mosque of Sultan Ahmed, Istanbul, on a prominent site on the Hippodrome complementary to that of S. Sophia, is distinguished by its six minarets. Four enormous piers dominate the interior and carry a dome which is buttressed, as in Shehzade Mosque, by four subsidiary half-domes... It is noted for its predominently blue Iznik tilework — whence it derives the name 'The Blue Mosque".

— Sir Banister Fletcher, A History of Architecture, p441.

Reported to be designed by Sedefkar Mehmed Aga ('Mehmet Aga', Turkish architect and craftsman, d. 1622).
