Sultan Ahmed Mosque
The exterior of the mosque itself boasts 66 domes and semi domes in a pyramidal arrangement, as well as two minarets. The main dome measures in height, and is supported by four flanking semi-domes. The dome plan of the New Mosque is based on the earlier Şehzade Mosque designed by Mimar Sinan, and on Sedefkar Mehmed Agha's Sultan Ahmed Mosque.
