Sultan Ahmed Mosque

The mosque has one big dome in the middle.

Around it are four half-domes, like big shells. Around those are even smaller domes. It looks like a hill of domes! Lots of windows let in the light.

Over the middle of the prayer hall rises a dome 23.5 meters across and 43 meters high. Four huge pillars hold it up, and half-domes and smaller domes step down around it like a cascade.

More than 250 stained-glass windows let daylight pour in, and there is room inside for about 10,000 worshipers. Outside, each minaret has small balconies around it.

Britannica gives the central dome as 23.5 m (77 ft) in diameter and 43 m (141 ft) high, supported by four large pillars and surrounded by cascading smaller domes; more than 250 stained-glass windows light the interior, which holds about 10,000 worshipers. The carved marble minbar (pulpit) is placed so that the imam can be heard anywhere in the mosque. Wikidata lists the building's height as 64 m and its length as 82 m.

Go Turkiye, the official tourism site, mentions arched stained-glass windows and a wrought-iron chandelier at the entrance to the prayer hall. Each minaret carries balconies (serefe); Britannica notes that six minarets, rather than the standard four, are one of the building's best-known features.

Inside, the walls are covered with shiny tiles.

The tiles show flowers, trees and patterns. Outside is a big, airy courtyard.

The mosque is famous for its tiles from Iznik, a town in Turkey known for fine pottery. More than 20,000 handmade tiles line the inside, decorated with flowers, trees and patterns, mostly in blue and green.

Above the tiles, the walls and domes are painted with patterns, mostly in blue. Outside the prayer hall is a large, airy courtyard where visitors can stroll before going in.

Britannica counts more than 20,000 handmade Iznik tiles lining the interior, richly decorated with flowers, trees and abstract patterns, with painted motifs, generally blue, on the walls above them. Hurriyet describes the tiles as green and blue, and the half-domes and central dome as adorned mainly with blue pen work.

The 2017 restoration conserved the tiles, the pen work, the marble floors of the inner court and the kundekari woodwork. Go Turkiye recommends the airy courtyard as part of a visit, and Britannica notes that the mosque is open to tourists when it is not in use for worship.

People still come to pray in the mosque.

Visitors are welcome to look inside too. It is a calm and peaceful place. Next to the mosque is the tomb of Sultan Ahmed.

The Sultan Ahmed Mosque is still a working mosque, where Muslims come to pray five times a day, and it welcomes visitors from around the world when it is not in use for prayer. The Fatih Municipality describes it as hosting millions of local and foreign visitors.

Go Turkiye, the official tourism site, calls it an active place of worship that visitors can see for themselves. Next to the mosque, a tomb building holds the graves of Sultan Ahmed I and his wife Kosem Sultan.

The mosque functions both as a place of worship and as one of Istanbul's most visited landmarks; the Fatih Municipality described it in 2023 as hosting millions of local and foreign tourists. Go Turkiye notes that the tombs of Ahmed I and his wife Kosem Sultan stand in a mausoleum beside the mosque.

Its setting matters too: UNESCO's description of Istanbul highlights the city's skyline of domes and minarets, built up over centuries by Byzantine and Ottoman architects, in which the Sultan Ahmed Mosque and Hagia Sophia face each other across a public square.
