The Blue Mosque is not merely a structure; it is a practicing mosque where devotees can pray under a blue-hued dome from where the masjid takes its name. Calligraphic inscriptions from the Qur’an on tablets reinforce its identity as a place of worship. Twenty thousand Iznik tiles with floral and fruit designs command the interior walls. Light emanates from over 200 stained-glass windows and the hanging chandeliers that hover much closer to the red-carpeted floor than the ceiling.
