Sultan Ahmed Mosque (Blue Mosque)
Look up at the blue — built by Ottoman Sultan Ahmed I between 1609 and 1617, this mosque's half-domes and main dome are covered inside with hand-painted brushwork in predominantly blue hues, complemented by blue, green, and white Iznik tiles, which is why Europeans came to call it the Blue Mosque. It stands as the final statement in two centuries of architectural dialogue between Ottoman mosques and Byzantine churches: the main dome measures 23.5 m in diameter and rests on four massive elephant-foot piers. But this is more than a prayer hall — it was conceived as a complete külliye, an Ottoman religious-civic complex encompassing a mausoleum, madrasa, soup kitchen, bazaar street, and hospital. It rewards a slow walk, taking in the smaller corners scattered around the old Hippodrome, each with its own story.

Painted Dome Ceiling
The name 'Blue Mosque' comes from directly above you. The undersides of the half-domes and main dome are not tiled but painted — a technique called kalem işi (literally 'pen work'), where brushstrokes in predominantly blue pigment cover the surface stroke by stroke. It is this painted blue that gave Europeans their name for the building. The entire decorative system was designed by Ottoman court architect Sedefkâr Mehmed Ağa. Below, the lower walls are sheathed in tiles; but as the eye travels upward, blue pigment increasingly takes over, drawing the gaze all the way to the apex.
Forecourt and Outer Courtyard
Before you reach the prayer hall, you pass through a forecourt nearly as large as the mosque itself. Its arcade facade closely follows the model set by the earlier Süleymaniye Mosque, differing mainly in the addition of small turrets over the corner domes; continuous arcades run around all four sides, with ablution facilities on each flank. At the center stands a large hexagonal fountain — which looks surprisingly small in a courtyard this expansive. The narrow, ceremonial entrance gateway into the courtyard deliberately sets itself apart from the surrounding arcade in its architectural treatment, making a distinct visual statement.

Minarets
Six minarets make this mosque instantly recognizable on the Istanbul skyline. Four rise from the corners of the prayer hall, each with three şerefe (projecting balcony tiers) for the call to prayer; two more stand at the corners of the outer courtyard with two şerefe each. All six are pencil-shaped with conical caps, and each şerefe is carried on a bracket of muqarnas — the geometric honeycomb ornament found throughout Islamic architecture. Six minarets was, at the time, unique among Ottoman mosques — even the Grand Mosque in Mecca had only six — and the sultan was criticized after completion for presuming to equal the holiest site in Islam.

The Mystery of the Six Minarets
Six minarets — a number that sparked a controversy when the mosque was completed. At the time, the Grand Mosque in Mecca also had six, and the sultan was accused of placing himself on a par with the holiest site in Islam. One popular story holds that the architect misheard the sultan's request for altın minare (golden minarets) as altı minare (six minarets), inadvertently creating the controversy. All six shafts are fluted cylinders topped with slender conical caps; the four at the corners of the prayer hall each have three şerefe (balcony tiers), while the two at the courtyard corners have two each. Every tier rests on a bracket of muqarnas ornament.

Madrasa
The madrasa (Islamic theological school) stands just outside the northeast wall of the mosque's outer courtyard, completed around 1620. Its plan follows the classical rectangular courtyard type: the yard is enclosed by arcaded, domed porticoes, with a row of domed student cells behind them — twenty-four in total. Two details set it apart from earlier madrasas: there is no formal monumental gateway at the entrance, and the dershane (main lecture hall, covered by a large dome) is located not at the center of one of its walls but in a corner of the building.
