In his memoir Istanbul, Turkey’s most famous writer Orhan Pamuk describes the particular kind of beauty strangers encounter in his city:

“A crumbling wall, a wooden tekke – condemned, abandoned and now fallen into neglect – a fountain from whose spouts no water pours, a workshop in which nothing has been produced for eighty years, a collapsing building, a row of houses abandoned by Greeks, Armenians and Jews … none of these things look beautiful to the people who live amongst them; they speak instead of squalor, helpless, hopeless neglect. Those who take pleasure in the accidental beauty of poverty and historical decay, those of us who see the picturesque in ruins – invariably, we’re people who come from the outside.”

Last week I had the pleasure of being an outsider in Istanbul. The beauty I encountered there was unlike any I’ve experienced before.

Sunset in Istanbul

There is the obvious beauty of the city’s magnificent skyline – particularly at sunset, when the silhouettes of mosques and ancient towers merge with the starker contours of the skyscrapers and cranes– and everything , including the glittering Bosphorus, is bathed in an orange glow.

But there is a different kind of beauty too – a fragile kind, which makes you feel that the entire city is held together by the most delicate of threads and that, if you were to tread too hard or in the wrong place, the entire metropolis could crumble before you.

This fragility is everywhere. It is in the wooden houses, with their crooked windows and shabby fronts and the chipped paint on the doors. It is in the young waiters outside restaurants, who – having failed to lure you in with a flashy smile and cheeky soundbite, return with resignation to the car-racing games on their mobile phones.

It was in the way our taxi driver whizzed through the city without a seat belt – getting lost in the old town and shouting at other drivers for directions yet saying nothing to us. It was in the way young boys wove through the heavy traffic selling bottles of water in the searing heat.

It is in the chaos at the Grand Bazaar, where the individual spiels of hundreds of vendors selling you the same wares are at once farcical and endearing. It is in the way they make you feel special though you know you are not.

At the waterfront, the cries of men selling Hugo Boss perfume, corn-on-the-cobs, selfie-sticks and even, apparently, Viagra,  compete with the blare of the ships’ horns on the Bosphorus.  It is a clamour suggestive of both hope and despair.

Pamuk ascribes Istanbul’s peculiar melancholy to the decline of the Ottoman Empire – to a collective mourning for what was and never again will be.

If the source of Istanbul’s  beautiful fragility lies in its history – it is nevertheless in the scramble of every-day life on the streets where it is best preserved.

Fragility can take many forms.

Before I went to Istanbul, I consulted the websites of several countries’ embassies to read their advice for travellers. In the days before my trip, there had been violence in the south of the country and gunfire outside a palace in Istanbul. There was also, apparently, a specific terror threat to the city’s public transport network.

Controlled explosion at Taksim Square

As so often happens, my fears dissipated as soon as I set foot in the city and became distracted by its magnificence.

But as I approached Taksim Square for the first time, my unease returned. The area had been cordoned off and was encircled by police vans. Crowds had gathered to watch a man in a bomb suit make his way towards the towering statue of Attaturk, the founder of modern Turkey.

The explosion terrified the pigeons into flight

The man carried out a controlled explosion – terrifying a flock of pigeons into flight. Its power sent a shiver coursing down my spine.

Moments later, the police were gone

and the square was once again teeming with people. It was if nothing had happened.
