10 Most Beautiful Mosques in Istanbul to Visit

Visiting the mosques is, in my honest opinion, the single best free thing you can do in Istanbul. You walk in off a noisy street, slip off your shoes, and suddenly you are standing under a dome the size of a small stadium with light pouring through stained glass. No ticket for most of them, no queue half the time, just centuries of stonework and the smell of carpet and old wood.

This is my pick of the 10 most beautiful mosques in Istanbul, the ones I actually send friends to. For each I have added what it looks like inside, why it matters, and the simplest way to get there. First, the boring-but-important bit that trips people up at the door.

How should you dress to visit a mosque in Istanbul?

Cover up, keep it simple, and you will be fine. The rule is the same at every working mosque in the city.

Women: hair, shoulders and knees covered. A light scarf laid loosely over the head is enough, you do not need a full veil. Long trousers or a long skirt plus a top that covers the elbows works perfectly.

Men: shoulders and knees covered. Long shorts that pass the knee are usually accepted, but I would wear long trousers and a t-shirt to avoid any awkward conversation at the entrance.

If you turn up underdressed, the bigger mosques (the Blue Mosque, Suleymaniye) lend out wraps and scarves free of charge at the door. For hygiene I still bring my own scarf rather than reuse a shared one. If you want the full breakdown before you pack, this guide on what to wear in Istanbul is worth a read.

Two practical things that matter more than people expect. Working mosques close to tourists during the five daily prayers, and stay shut a bit longer around Friday noon prayer, so the longest closures land roughly between 12:00 and 14:30 on Fridays. Aim for mid-morning on a Tuesday, Wednesday or Thursday and you will more or less have the place to yourself.

1. Hagia Sophia

We have to start here, because nothing else on earth quite matches it. The Hagia Sophia (Ayasofya) began as a Byzantine cathedral, commissioned by Emperor Justinian and finished in 537. Eastern Roman emperors were crowned under that vast dome. After the conquest of Istanbul in 1453 it became a mosque, was turned into a museum in 1935, and reverted to a working mosque in 2020.

The practical change you need to know for 2026: the ground-floor prayer hall is free, but foreign visitors now pay to reach the upper galleries where the famous Byzantine mosaics are, and at the time of writing the official entrance fee sits at around €25. An ongoing restoration means parts of the interior can be screened by scaffolding, so check before you build a whole afternoon around it. The full story is worth reading first in our Hagia Sophia facts and history guide.

It sits in Sultanahmet, right across the square from the Blue Mosque. Tram T1 to Sultanahmet drops you a two-minute walk away.

2. The Blue Mosque (Sultanahmet Mosque)

The Sultan Ahmed Mosque earns its nickname from the roughly 20,000 hand-painted Iznik tiles lining the upper walls, which throw a soft blue light through the whole interior. It was built between 1609 and 1616 by Sedefkar Mehmet Aga, a pupil of the great Sinan, and its six minarets famously caused a stir at the time, since only the Kaaba in Mecca had as many.

Good news for visitors: the mosque came out of its long, six-year restoration and the main dome and tiles are fully on show again. Entry is still free, with no ticket required, which makes it the best-value half hour in the old city. Go early, the queues build fast by late morning. It faces Hagia Sophia across the gardens, and you can read more in our piece on the Blue Mosque (Sultan Ahmed Mosque). The whole Sultanahmet district deserves a slow day on foot.

3. Suleymaniye Mosque

If I could only send you to one mosque, it would be this one. The Suleymaniye is Sinan’s masterpiece, built between 1551 and 1558 for Suleyman the Magnificent, and it sits high on a hill with one of the finest free views over the Golden Horn. The complex around it once held hammams, madrasas, a hospital, libraries and soup kitchens, a whole little city of charity. The dome rises about 53 metres, and the four minarets are deliberately different heights.

It is calmer and far less crowded than the Blue Mosque, which is exactly why I love it. Stay for the terrace at the back and the cluster of old tea gardens and bean restaurants on the streets below. Full background lives in our Suleymaniye Mosque history and facts guide. Get off the Kabatas to Bagcilar tram at Laleli-Universite and walk up, or come over from the nearby Grand Bazaar.

4. Ortaköy Mosque (Büyük Mecidiye Mosque)

This is the postcard one, the small white mosque standing right at the water’s edge with the Bosphorus Bridge rising behind it. Finished in 1854 under Sultan Abdulmecid, it leans into a Baroque style that was fashionable in European palaces of the time, all carved stone outside and floral marble inside, lit on four sides by daylight bouncing off the water.

It is tiny, so the real attraction is the setting. Come at sunset, grab a kumpir (loaded baked potato) from the famous stalls on the square, and watch the light go pink over the strait. Our Ortaköy Mosque guide covers the visit in detail. From Besiktas it is a short bus ride or a pleasant 20-minute walk along the shore.

5. Eyüp Sultan Mosque

This is the most spiritually charged spot on the list. Eyüp Sultan stands on the upper reaches of the Golden Horn, beside the tomb of Abu Ayyub al-Ansari, one of the Prophet Muhammad’s companions, which is why it draws huge numbers of worshippers, especially on religious holidays and during Ramadan. The original dates to 1458, with the building you see today taking shape around 1800. The interior tiles are stunning and the courtyard, with its ancient plane tree and fountains, is genuinely peaceful.

Pair it with a cable-car ride up to Pierre Loti Hill for tea and a view back down over the water. Read more in our Eyüp Sultan Mosque guide. Buses and the T5 tram along the Golden Horn both reach Eyüp easily.

6. Mihrimah Sultan Mosque (Üsküdar)

Sinan again, this time in 1548, building for Mihrimah, the favourite daughter of Suleyman the Magnificent. The story goes that Sinan was quietly in love with her, and you can almost believe it: there is no showy decoration here, just elegant, perfectly judged proportions. It sits right by the ferry pier in Üsküdar on the Asian side, so it makes a natural first stop if you cross the water.

Take the Marmaray under the Bosphorus to Üsküdar, or, much nicer, ride a public ferry over and watch the European skyline shrink behind you. Üsküdar’s tea gardens and the Maiden’s Tower out in the strait are both close by.

7. Fatih Mosque

Fatih is the first great imperial mosque built after the Ottoman conquest, and it gives its name to the whole surrounding district. The original complex from 1470 was enormous: 16 madrasas, a hammam, kitchens, a library, a guest house and a hospital, with the tomb of Mehmed the Conqueror himself in the grounds. The mosque you see now was largely rebuilt after an 18th-century earthquake, which is why it mixes classical Ottoman lines with later Baroque touches.

This is a deeply local, conservative neighbourhood, and the Wednesday street market nearby is one of the best in the city. Buses from Eminönü run up here, and it is an easy add-on to a Suleymaniye morning.

8. Rüstem Pasha Mosque (Eminönü)

My favourite small mosque in Istanbul, and the one most visitors walk straight past. Sinan built it in the 1560s for the Grand Vizier Rüstem Pasha, and the inside is wall-to-wall Iznik tiles in reds, blues and greens, the densest and finest collection of them anywhere in the city. Stepping in really does feel like walking into a tile museum. A careful restoration completed in recent years has the tilework looking superb.

The catch is finding it. It hides above the shops just behind the Spice Bazaar, reached by a discreet staircase, so look up for the small signs. It is free, with a donation box at the door. Combine it with a wander through the Spice Bazaar right next door. Tram, bus and the Marmaray all stop at Eminönü.

9. Beyazıt Mosque

Beyazıt is one of the oldest surviving imperial mosques in Istanbul still close to its original form, built for Sultan Bayezid II in the early 1500s. The courtyard is the star: paved in marble and red porphyry, ringed by 24 domes on 20 ancient columns. The main dome spans about 17 metres and rests on the four broad piers that builders nicknamed “elephant feet”.

It sits on Beyazıt Square right at the main gate of the Grand Bazaar, so it is an easy pause in the middle of a shopping day. Take the tram and get off at Beyazıt-Kapalıçarşı.

10. Taksim Mosque

The newcomer, and proof that the tradition is still alive. Opened in 2021 after four years of work, the Taksim Mosque stands on the edge of Taksim Square in a clean, contemporary take on art deco. Across three levels it can hold around 3,000 worshippers, and the design deliberately keeps the square open rather than dominating it.

It is worth a look if you are already on this side of town, since it shows how mosque architecture keeps evolving rather than freezing in the 16th century. Just ride the metro to Taksim and you are at the door. From here, İstiklal Avenue and the whole Beyoğlu nightlife scene are a short stroll away.

Which Istanbul mosques are worth your time?

If you only have one day, do Hagia Sophia and the Blue Mosque because they face each other in Sultanahmet, then climb up to Suleymaniye for the view and the quiet. With a second day, cross to the Asian side for Mihrimah Sultan, or chase tiles at Rüstem Pasha. Almost all of them are free, all of them ask the same modest dress code, and all of them reward turning up early before the tour groups arrive. Bring a scarf, slip off your shoes, and take your time.
