Sultan Ahmed Mosque (Blue Mosque), Istanbul

Architecture and interior

Designed by Sedefkar Mehmet Agha, a pupil of the imperial architect Sinan, the mosque is notable for its large central dome surrounded by cascading semi-domes, a broad courtyard, and a striking array of six slender minarets. The interior is famed for thousands of Iznik-style blue tiles that give the mosque its popular name and for its stained glass windows, calligraphic panels, and finely detailed ornamentation. Contemporary accounts describe the decorative work as meticulous and jewel-like.

History and complex

Construction took place during the reign of Sultan Ahmed I (1609–1616) as part of a larger külliye, or religious and social complex. In addition to the mosque itself, the complex historically included a madrasa and a hospice or imaret, and the tomb of the founder is located within the precinct. The project expressed both piety and imperial prestige during the later Ottoman period and sought to rival earlier imperial mosques.

Uses and visiting today

The Blue Mosque continues to serve regular Muslim worship while also attracting large numbers of visitors. As an active mosque, it closes to tourists during prayer times and asks visitors to observe modest dress and respectful behavior. Guided tours and general sightseeing commonly highlight its tile work, dome structure, and views across the historic Sultanahmet area.
