The Blue Mosque, officially the Sultan Ahmed Mosque (Sultanahmet Camii), is the building most travellers picture when they think of Istanbul’s skyline. Sultan Ahmed I commissioned it in 1609 and the architect Sedefkâr Mehmed Ağa finished it in 1616, when Ahmed was still in his twenties. It is still an active mosque, which shapes everything about a visit: opening times, dress and where you walk.
Entry is free. The mosque sits in the Historic Areas of Istanbul, a UNESCO World Heritage property, and Go Türkiye is the official tourism portal if you want to cross-check anything before you travel.
Hours and Prayer Closures (as of 2026)
The mosque opens to visitors from roughly 08:30 until dusk, but it closes to tourists for each of the five daily prayers. Expect each closure to last somewhere between 60 and 90 minutes, and the times shift through the year with sunrise and sunset. A schedule is posted at the visitor gate, and any prayer-times app will give you the same information for Istanbul.
- Friday: the midday service is the main weekly prayer, and tourists are generally let back in only after about 14:30.
- Best windows: the hour after opening, and mid-afternoon between the midday and afternoon prayers outside Friday.
- Religious holidays: hours change during Ramadan and the two Eid holidays, and the mosque can be very busy with worshippers. Plan Sultanahmet around other sights on those days.
Dress Code
The rules are simple and enforced at the door.
- Knees and shoulders covered for everyone. Shorts and sleeveless tops are turned away.
- Women cover their hair. Free headscarves and wraps are handed out, but bringing a light scarf of your own is more comfortable.
- Shoes come off. You carry them in a free plastic bag, so wear socks you are happy to be seen in on a stone floor.
- Keep voices low, do not walk in front of anyone praying and avoid flash photography.
The Visitor Entrance
Visitors and worshippers use different doors. Tourists queue at the entrance on the Hippodrome (Atmeydanı) side, while the main courtyard gate is for people attending prayers. Follow the signs and the queue barriers and you will not go wrong. In peak summer the queue can be 20 to 40 minutes, longer just after a prayer closure ends because everyone floods back in together.
What to See Inside
The interior is the reason to queue. The walls and galleries carry more than 20,000 hand-painted İznik tiles in blues, greens and whites, which gave the mosque its English nickname. Around 260 windows fill the main hall with light, and the central dome rests on four large “elephant foot” piers. The mosque is unusual for having six minarets, a detail that reportedly caused controversy because it matched the number at the Great Mosque of Mecca at the time.
Allow 30 to 45 minutes inside, plus the queue. The tourist section is at the back of the prayer hall behind a barrier, so you view the space rather than walk through its middle. Outside, the courtyard is arguably the best part for photography, with its arcades, domed ablution fountain and a clear view of the cascading domes.
How to Get There
The nearest tram stop is Sultanahmet on the T1 line, a 3-minute walk. T1 runs from Kabataş through Eminönü and Sultanahmet toward Bağcılar, so it connects with the ferries at Eminönü and Karaköy. Hagia Sophia is directly across the park, about 5 minutes on foot, and the Basilica Cistern is a 3-minute walk. If you are staying in Beyoğlu, take the F1 funicular from Taksim to Kabataş and change to the tram. An Istanbulkart makes every ride cheaper.
Making a Plan
Most people visit the Blue Mosque together with its neighbours. A sensible order is the mosque first thing in the morning, Hagia Sophia next, then the Basilica Cistern and Topkapi Palace after lunch. Because the prayer closures break up the day, check times before you build a schedule rather than after.
If you would rather have the history explained, several Sultanahmet walking tours cover the mosque, Hagia Sophia and the Hippodrome with a licensed guide and arrange the queue for you. Our best tours in Istanbul guide compares the main options, and the Istanbul things to do guide shows where this fits in a wider trip.
Tips
- Beware of touts at the gate offering paid “skip the queue” entry. The mosque has no ticket.
- Bring a small bag, since large backpacks may be refused or slow the security check.
- Visit again at dusk from the park. The floodlit domes are a different view from the daytime interior.
- Photography is allowed inside without flash, but do not photograph worshippers.
