Built by Sultan Ahmet I as a part of a large complex, among the Turkish people it is called Sultan Ahmet Mosque. However, tourists fascinated with the beautiful blue tiles always remember it as the Blue Mosque. The complex consisted of a mosque, tombs, medreses, fountains, a health center, kitchens, shops, a bath, rooms, houses and storehouses.

Ahmed I, who ascended the throne at the age of fourteen was an extremely religious-minded sultan, who displayed his religious fervor in his decision to construct a mosque to compete with Ayasofya. For the site, a suitable place was long sought before the decision was taken. At last the mosque decided to build on the site of the palace of Ayse Sultan. The owner of the palace was compensated and the site prepared by the architect Mehmed Aga, who began the construction in 1609 and the architect poet says, " This great work is completed in 1617 ".

A 19-year-old Sultan started digging ceremoniously in the presence of high officials until he was tired. Thus began the construction in 1609 which continued until it was finished in 1616. An interesting fact about Sultan Ahmet is that he ascended to the throne at the age of 14 as the 14th ruler and died only 14 years later. Being close to the Topkapi Palace, Sultan Ahmet Mosque was regarded as the Supreme Imperial Mosque in Istanbul. Even though the palace was left and the sultan moved to the Dolmabahce Palace, Sultan Ahmet Mosque shared this pride with the Suleymaniye Mosque. The architect was one of the apprentices of Sinan, Sedefkar Mehmet Aga. He designed one of the last examples of the classical period's architectural style.

The mosque is situated in a wide courtyard which has five gates. There is an inner courtyard next to the mosque with three entrances. The inner courtyard is surrounded by porticos consisting of 26 columns and 30 domes. The sadirvan in the middle is symbolic, because the actual ones are outside on the walls of the inner courtyard. There are three entrances to the main building, one from the inner courtyard and two from both sides of the building. There are four minarets at the corners of the mosque having three serefes each. The two minarets at the far corners of the courtyard have two serefes each. There are six minarets in all, each of which is fluted.


The interior of the mosque is a square with a width of 51.65 m / 170 ft and a length of 53.40 m / 175 ft covered by a dome. The main dome rests on four semi-arches and four pendentives.

The diameter of the dome is 22.40 m / 73.5 ft and the height is 43 m / 141 ft. The four piers carrying the dome are called elephant legs as each has a diameter of 5 m / 16.4 ft.The narrow panels between these windows on the interior are covered with 17th century tiling.

The most striking feature of this tiled decoration is a band of inscription in reserve white over a dark blue back ground around the interior. There are 260 windows which do not have original stained glasses any longer. The walls all along the galleries are covered with 21 thousand Iznik tiles having many flower motifs in a dominant blue color.A total of 21043 tiles have been used in the interior

On summer evenings, generally beginning at 8:00 p.m., a sound-and-light show, which is worth seeing, is presented between the Blue Mosque and the Hagia Sophia. The languages of the show which are Turkish, English, French and German rotate daily with one each night.
