Niobe’s Hidden Istanbul

Discovering the Nakilbent Cistern Beneath a Carpet Shop

There are moments when you think you already know Istanbul.

You have walked through Sultanahmet, admired the Blue Mosque, stood beside the ancient Hippodrome and looked at the enormous curved remains of the Sphendone.

And then, completely unexpectedly, Istanbul opens another door.

This happened to me on an ordinary afternoon.

I was walking near the old Hippodrome when I noticed a beautiful carpet displayed in the window of a traditional carpet shop. It immediately caught my attention.

So, naturally, I stopped.

Before exploring further, I decided to sit down and enjoy a cup of hot Turkish tea.

There is something wonderfully Istanbul about drinking tea while surrounded by beautiful carpets, colors, patterns and the quiet atmosphere of a traditional shop.

I was admiring the carpet in the window when curiosity got the better of me.

I wanted to see it closer.

And that was when my little Istanbul adventure suddenly became something completely different.

One carpet led to another discovery

I stepped inside the shop.

The staff welcomed me and began showing me some of the carpets. One after another, beautiful patterns appeared, each with its own colours, textures and character.

But then something caught my attention.

The staff proudly showed me something underneath the shop.

At first, I thought perhaps it was simply another part of the building.

Then I realized...

There was something ancient beneath my feet.

A staircase led down.

And suddenly I was no longer standing in an ordinary carpet shop.

I was going underground.

What was hiding beneath the carpet shop?

I could hardly believe what I was seeing.

Hidden beneath the modern shop was an ancient Byzantine cistern, known today as the Nakilbent Cistern, also called the Nakkas Cistern or Nakilbent Street Cistern.

The cistern is located extremely close to the Sphendone of the ancient Hippodrome of Constantinople and is recorded as a Byzantine water structure dating to around the 5th century. It is accessible through the carpet shop with permission.

I had walked past this area before.

How many other people had done the same?

Thousands of visitors come to Sultanahmet every day, photographing the monuments above ground.

Yet underneath the streets, another Istanbul is waiting.

A quieter Istanbul.

A darker Istanbul.

An Istanbul of stone, brick, water and forgotten stories.

From carpets to Byzantine Istanbul

This is what fascinates me most about Istanbul.

You can enter a shop looking at a beautiful Turkish carpet...

And a few minutes later, you can find yourself standing inside a structure that belongs to a completely different chapter of the city's history.

Above me was modern Istanbul.

Around me were carpets and ceramics.

But beneath the floor was the world of Constantinople.

It felt almost impossible.

The Nakilbent Cistern is associated with the area around the ancient Hippodrome, one of the most important spaces of Constantinople. The nearby Sphendone formed the enormous curved southern end of the Hippodrome and remains one of the most impressive surviving traces of the ancient structure.

And suddenly I understood something about Istanbul:

You don't always have to go looking for history. Sometimes history is waiting underneath you.

My unexpected underground adventure

I had originally stopped because of a carpet.

I stayed because of curiosity.

And I went underground because the people inside the shop offered to show me a part of Istanbul that I never expected to find.

That is the beauty of exploring this city without rushing.

Sometimes the most memorable experiences aren't the famous monuments you planned to visit.

They are the discoveries you never knew existed.

A small doorway.

A friendly invitation.

A cup of hot tea.

A beautiful carpet in a window.

And then...

A staircase disappearing into the past.

Istanbul has more than one level

Standing inside the Nakilbent Cistern, I couldn't stop thinking about how many layers Istanbul has.

There is the Istanbul we see every day.

The cafes.

The restaurants.

The colorful shops.

The mosques.

The streets filled with visitors.

Then there is the Istanbul beneath it all.

Ancient walls.

Cisterns.

Old foundations.

Byzantine structures.

Roman remains.

Ottoman additions.

Centuries of history built one on top of another.

The Nakilbent Cistern is one of those places where the layers suddenly become visible.

And that is what made this discovery so special to me.

From one hidden treasure to another

What started with a carpet didn't end with a carpet.

The shop itself became part of the story.

The carpets above represented the artistic traditions of Turkey.

The ceramics and beautiful objects around me reflected another part of Istanbul's cultural world.

And underneath them was a Byzantine water structure that had survived for centuries.

It was almost as if the shop was telling me:

"Look carefully. Istanbul always has something underneath."

And perhaps that is the best advice I can give anyone visiting this city.

Look carefully.

Don't always follow the obvious path.

Turn into the little street.

Look inside the old shop.

Stop for tea.

Talk to people.

Ask questions.

Because sometimes a simple moment of curiosity can lead you somewhere extraordinary.

My new secret in Sultanahmet

I left the cistern astonished.

I had come for a closer look at a carpet.

Instead, I discovered a hidden chapter of Byzantine Istanbul.

The Nakilbent Cistern may not have the fame of the Basilica Cistern, but perhaps that is part of its charm.

It feels like a discovery.

A secret hidden in plain sight.

And now, whenever I walk near the ancient Hippodrome and see the Sphendone, I know that another world is waiting just a few steps away — underneath a carpet shop.

So, was this my last unexpected discovery in Istanbul?

Absolutely not.

Because I have learned something during my travels:

In Istanbul, the story is never quite finished.

Sometimes...

the story just starts when you open the door.
