About Blue Mosque

The Blue Mosque was built for Sultan Ahmed I in the early seventeenth century and faces Hagia Sophia across the Hippodrome square. Its prayer hall is lined with thousands of blue Iznik tiles beneath cascading domes and six minarets. The Grand Bazaar, Topkapı Palace and the Bosphorus ferry piers are all within walking distance. Spring and autumn bring mild weather and thinner crowds, summer is hot and busy, and winter stays grey and quiet.

Travel Tips

01Prayer Time Closures
Sultan Ahmed Mosque closes to tourists during prayer times - check the day's schedule and arrive between slots. Fridays are busiest; early morning is calmest.
02Dress Code Strict
Cover shoulders, legs, and women's hair before entry; wraps are often available but bring your own scarf to save time. Remove shoes and carry them in the provided bag.
03Combo with Hagia Sophia
Visit with Hagia Sophia across the square but expect separate queues and ticket rules. Midday light is harsh for photos; late afternoon is softer on the courtyard.
04Courtyard Crowds
The courtyard and ablution area get congested - keep bags close and move patiently. Stay quiet inside; this is an active place of worship, not only a monument.
