The Sultan Ahmet Mosque is a historic mosque in Istanbul, Turkey. Definitely Istanbul’s most photogenic building. It was the grand project of Sultan Ahmet I , whose tomb is located on the north side of the site facing Sultanahmet Park.
The mosque’s architect, Sedefhar Mehmet Ağa, managed to orchestrate the sort of visual wham-bam effect with the mosque’s exterior that Aya Sofya achieved with its interior. Its curves are voluptuous, it has six minarets (more than any other mosque at the time it was built) and its courtyard is the biggest of all of the Ottoman mosques.
The mosque is popularly known as the Blue Mosque, tens of thousands of blue Iznik tiles adorning the walls of its interior, there are 260 windows and the central prayer space is huge.
