Built in 1616 on the orders of Sultan Ahmed I, the Blue Mosque (Sultanahmet Camii) still defines Istanbul's skyline with its six minarets and cascading domes. Step inside and over 21,000 hand-painted Iznik tiles cast the nave in a cool, luminous blue — a sight that never loses its power.
Few monuments carry the weight of history so lightly. The Blue Mosque stands at the heart of Sultanahmet Square, directly across from Hagia Sophia, on the former site of the Byzantine Great Palace. It was the last great imperial mosque commissioned during the classical Ottoman period, and it remains an active place of worship — something that gives it a warmth that many landmark sites lack.
History: The Sultan Who Built a Controversial Mosque
Sultan Ahmed I came to the throne at thirteen. By 1609 — still only twenty years old — he had commissioned a mosque that would challenge everything before it. He assigned the project to Sedefkâr Mehmed Ağa, a master architect trained under the great Sinan, and gave him instructions to build something worthy of standing opposite the greatest Byzantine church in the world.
The result, completed in 1616, was a mosque with six minarets — a number previously reserved for the mosque at Mecca. The outcry among religious scholars was immediate. Ahmed's solution was diplomatic: he funded a seventh minaret at the Grand Mosque in Mecca, restoring its unique status. The story is still told to visitors today.
Ahmed I died the same year his mosque was completed, aged twenty-seven. He is buried in the türbe (mausoleum) on the north side of the building, along with his wife Kösem Sultan and three of his sons. The mosque he left behind would give Istanbul one of its most recognisable silhouettes for over four centuries.
Six Minarets: Still a Striking Sight
Most Ottoman imperial mosques have two or four minarets. The Blue Mosque's six remain unusual even by Istanbul standards. Their pencil-thin silhouettes rise in pairs at the corners and the middle of the facade, creating a visual rhythm that photographers have chased for four hundred years.
The best viewpoints are from the Hippodrome (At Meydanı) and from the terrace of Hagia Sophia's upper gallery. At dusk, when the LED lights switch on and the minarets glow against a deep blue sky, the square fills with people standing still, phones raised.
The mosque's dome structure is also exceptional: a central dome 23.5 metres in diameter is flanked by four semi-domes, which are in turn flanked by smaller domes — a cascading sequence that draws the eye upward both outside and in.
Inside the Blue Mosque
The name comes not from the exterior — which is the pale grey of limestone and lead — but from what you see the moment you pass through the inner doorway. The upper walls and dome are lined with more than 21,000 Iznik tiles, their dominant colour a deep, saturated cobalt blue. Combined with 260 windows (many of them modern replacements, but the overall effect of diffused light is preserved), the interior seems to breathe.
The nave is vast: the prayer hall measures roughly 53 by 51 metres. Four massive fluted columns — 5 metres in diameter, nicknamed the "elephant feet" by locals — support the central dome at a height of 43 metres. Between the columns, the open floor is covered in deep-red carpets arranged in rows of individual prayer spaces, a practical detail that also helps visitors understand the scale.
Inside the Blue Mosque — A Visual Walk-Through
The mihrab (prayer niche indicating the direction of Mecca) is made of finely carved white marble, and beside it stands the minbar — the pulpit from which the imam delivers the Friday sermon. Both are original seventeenth-century pieces. The carved wooden müezzin's gallery opposite, from which the call to prayer was once given inside the building, is also still intact.
A rope barrier separates the active prayer area at the far end from the non-prayer visitor zone at the entrance end. This is not merely symbolic: prayers are held five times daily, and during those times the mosque is closed to tourists. Respect is the baseline expectation; the vast majority of visitors observe it without being asked.
The Iznik Tiles: A Craft at Its Peak
The tiles were produced in the town of İznik (ancient Nicaea, in present-day Bursa province) at what historians regard as the peak of Ottoman ceramic art. The Blue Mosque commission came at a difficult time for the İznik workshops — demand had outstripped their capacity — and the quality of individual pieces varies. But the cumulative effect of 21,000 tiles covering the gallery level and upper walls is overwhelming.
The palette runs from white and cobalt blue through turquoise to a tomato red made from a raised slip of Armenian bole — a technique that appears slightly three-dimensional under raking light. Floral motifs dominate: tulips, carnations, roses, and cypress trees, all rendered with a fluency that no industrial process has since matched.
Get as close as you can to the tiles in the lower galleries during your visit. The detail is extraordinary — each bloom, each leaf individually drawn — and photographs rarely do justice to the depth of colour you see in person.
Around the Mosque: What Else to See
The Blue Mosque complex is larger than the prayer hall alone. Allow time for:
Sultan Ahmed I Mausoleum
The türbe on the northern side of the mosque complex contains the sarcophagi of Sultan Ahmed I, Kösem Sultan, and three sultans who followed. It is open to visitors and entry is free. The interior tile work is quieter than the mosque but no less refined.
Arasta Bazaar
Running along the south flank of the mosque, the Arasta Bazaar is a seventeenth-century covered market originally built to fund the mosque's upkeep. Today it sells carpets, ceramics, and textile work — mostly aimed at tourists, but the building itself is worth a look. The Mosaic Museum (Büyük Saray Mozaikleri) is located at the eastern end, displaying in situ Byzantine floor mosaics from the Great Palace.
Hippodrome: The open square immediately north of the mosque is built on the ancient Hippodrome of Constantinople, once a 100,000-seat chariot-racing circuit. Three original monuments survive: the Egyptian Obelisk of Thutmose III (c. 1450 BC), the Serpent Column from Delphi, and the Column of Constantine. All are visible from the mosque steps at no charge.
The Blue Mosque at Different Times of Day
The mosque reads differently at dawn, midday, and after sunset. The morning light from the east catches the dome's lead sheeting and turns it silver; at noon in summer the courtyard is harsh but the interior is cool and quiet between prayers; after dark the LED floodlighting renders the minarets and dome in near-photographic precision against a black sky.

Blue Mosque FAQ
Is the Blue Mosque free to visit?
Yes. Entry to the Blue Mosque is free for all visitors during non-prayer hours. Donation boxes are placed near the exit; contributions help with maintenance. There is no ticket, no queue system, and no booking required — you simply join the visitor entrance when the mosque is open.
How long does a visit take?
Most visitors spend 45 to 75 minutes inside. Budget an additional 20–30 minutes for the courtyard, the mausoleum, and a walk around the exterior. If you are combining it with Hagia Sophia and the Hippodrome in one morning, allow three to four hours for the whole cluster.
Why is it called the Blue Mosque?
The building's official name is Sultanahmet Camii (Sultan Ahmed Mosque). The Western nickname "Blue Mosque" comes from the colour of the 21,000 Iznik tiles lining the interior — predominantly cobalt blue and turquoise — which give the nave its distinctive blue-washed light.
Why does the Blue Mosque have six minarets?
Most Ottoman imperial mosques have two or four minarets. When Sultan Ahmed I commissioned six, it caused a religious controversy because the Grand Mosque in Mecca also had six — a number seen as uniquely sacred. Ahmed resolved the dispute by funding a seventh minaret for the Mecca mosque, restoring its precedence. The six-minaret silhouette has remained one of the most recognisable in Istanbul ever since.
When should I visit to avoid crowds?
Weekday mornings before 10:00 are the quietest. Summer afternoons (13:00–15:00) are the most crowded. Arriving just after a prayer reopening — when the previous crowd has left and the next wave hasn't arrived — can give you 15–20 relatively uncrowded minutes inside.
Do I need to cover my head?
Women must cover their hair. Men do not need to cover their heads. Free headscarves are available at the entrance for women who don't have one. Both men and women must cover their shoulders and knees; free wraps are also available for those wearing shorts or sleeveless tops.
Can I visit during prayer times?
No. The mosque closes to non-Muslim visitors approximately 30 minutes before each of the five daily prayers and reopens approximately 30 minutes after. On Fridays, the closure for the noon prayer (Cuma namazı) is longer — typically from around 12:30 to 14:30. The prayer schedule is posted at the entrance each morning.
What is the difference between the Blue Mosque and Hagia Sophia?
Hagia Sophia (Ayasofya) was built as a Christian cathedral in 537 AD and converted to a mosque in 1453; it was a museum from 1934 to 2020 and is now again an active mosque. The Blue Mosque was built as a mosque in 1616 and has remained one continuously. Both are active places of Muslim worship today, both are free to visit in non-prayer hours, and both can be visited in the same morning since they stand 200 metres apart.
Is there a dress code for men?
Men must cover their knees — shorts above the knee are not permitted. Sleeveless tops are also not allowed. Free wrap-around coverings are available at the entrance. There is no requirement to cover the head.
How do I get to the Blue Mosque from Istanbul Airport (IST)?
By public transport: take the M11 metro from IST to Gayrettepe, transfer to the M2 toward Yenikapı, then change to the T1 tram at Zeytinburnu or Yenikapı and ride to Sultanahmet (approx. 60–75 min total, fare with İstanbulkart). By private transfer: a private vehicle from IST to Sultanahmet takes 40–60 minutes depending on traffic, with no changes and door-to-door delivery.
How do I get to the Blue Mosque from Sabiha Gökçen Airport (SAW)?
By public transport: take the Havabus shuttle to Kadıköy, then a ferry to Eminönü, then walk or take a short tram ride to Sultanahmet (approx. 90–120 min). By private transfer: a private transfer from SAW is typically the most practical option for Sultanahmet, as the public transport connection is less direct than from IST.
Is the Blue Mosque wheelchair accessible?
There is a dedicated accessible entrance on the east side of the courtyard. The main prayer hall is on a single level and can be accessed by wheelchair. However, some parts of the complex (galleries, mausoleum) have steps. Call ahead via the mosque's management office if you require specific arrangements.
Can I combine the Blue Mosque with Topkapı Palace in one day?
Yes — it is one of the classic Sultanahmet day itineraries. Visit the Blue Mosque first thing (before 10:00), cross to Hagia Sophia, then walk up to Topkapı Palace after lunch. Buy Topkapı tickets online in advance; summer queues at the gate can be long. The Basilica Cistern fits neatly between the mosque and Hagia Sophia.
