Blue Mosque

Mosque · SultanahmetIstanbul,Türkiye

An Istanbul mosque lined with more than twenty thousand İznik tiles in cobalt and sea-green, lit by 260 windows and marked out by six minarets.

The Blue Mosque takes its English name from what covers its walls: more than twenty thousand İznik tiles in cobalt and sea-green, worked into tulips, carnations and cypresses. Some 260 windows, once glazed with coloured Venetian glass, spill light across them until the room seems to glow. Step inside and the domes rise in tiers, one lifting the eye to the next, until a painted crown floats far overhead. Outside, six minarets mark it out on the skyline. Sultan Ahmed I was barely nineteen when he ordered it, and with no great conquest to pay the way he drew on the imperial treasury, breaking with custom. Sedefkâr Mehmed Ağa, a pupil of Sinan, finished it in 1616, and the site was chosen so the mosque would stand across a garden from the Byzantine church it was meant to match. It is still a working mosque: five times a day the carpets fill with people at prayer, and visitors cross barefoot between prayers, shoes in hand, under the same vast ceiling.

Worth knowing

Good to know

The tiles glow best on the slant — İznik glaze catches light at an angle, so look sideways and upward as you move: cobalt at the base gives way to greens higher up.
Let low sun do the work — the ranks of coloured-glass windows are the mosque's real instrument. Morning or late-afternoon light angling through them sets the tiles glowing in a way flat midday never manages.
Approach from the Hippodrome — the mosque was composed to unfold as you walk: from the old chariot square the domes and half-domes stack into a pyramid gathering height toward the courtyard gate.
Treat it as prayer, not a museum — shoulders and knees covered, a scarf for hair, bare feet on the carpet; enter as if crossing into someone's devotion and the room changes.

Things to do

1
Follow the light up into the domes
Step just inside, stop before the crowd carries you on, and tilt your head all the way back. Let your eye climb from one dome to the next without rushing. Then move slowly across the floor until you find the spot where the filtered light pools bluest — usually near the eastern windows on a bright morning — and stand in that patch of colour.
2
Hunt for the ostrich eggs
Look up the long chains that suspend the low ring of lamps and search for the white ostrich eggs tucked among them. The old story goes they were hung there to keep spiders — and their cobwebs — away from the fittings. Once you spot one, you start seeing them everywhere.
3
See it and Hagia Sophia glowing at dusk
Stand in the gardens between the Blue Mosque and Hagia Sophia as the light fades and both begin to glow. Look from one to the other: a Byzantine church of the sixth century and the Ottoman mosque raised a thousand years later, each roofing a huge hall with one great dome, facing each other across the park.
4
Turn the side aisles into a hunt
Slip into the quieter side aisles, away from the central crush, and slow right down. The tilework changes as you walk, and a few panels break the rhythm outright — a stray colour, a pattern that appears nowhere else on that wall. Finding one is the whole game.
