Sultan Ahmed Mosque
The Sultan Ahmed Mosque stands out across Istanbul’s skyline, instantly recognizable by its massive central dome and six slender minarets. Built in 1617 for Sultan Ahmed I, this historic mosque remains a place of active worship today.
Visiting the Mosque
Respectful clothing is required for all visitors, and it is important to avoid visiting during prayer times. The main entrance is found through the courtyard on the southwest side. Shoes must be removed before stepping inside the prayer hall.
Inside the Blue-Tiled Prayer Hall
Once inside, the striking blue tiles give the prayer hall its famous nickname, the Blue Mosque. The impressive main dome is surrounded by smaller semi-domes, creating a spacious and light-filled atmosphere. The mihrab, a beautifully carved marble niche indicating the direction of Mecca, is especially well-lit and easy to spot. Nearby, the elegant minbar, or pulpit, stands in clear view from nearly every part of the hall.
