Basilica Cistern – Going Tourist In Istanbul

Share this article

We’d been meaning to revisit Istanbul’s Basilica Cistern (Yerebatan Sarnıcı) for years, but somehow hadn’t got around to it.

The thing is, when you’ve visited a city so many times, you get settled into wandering streets, previously unknown shops and markets, eateries and bars.

Once you’ve visited all the main sights, that’s when you start to really get to know a place. And for us, with Istanbul, that’s definitely been the case.

All those world famous, centuries old UNESCO World Heritage sites watching over us. But, in recent years, neglected by us.

Until our last trip, that is, where we were determined to once more set foot in places like Sultanahmet Camii (Blue Mosque) and Yerebatan Sarnıcı; better known in English as the Basilica Cistern.

We’re not the best sightseeing people.

Queues, entrance fees, camera at the ready and chuntering to yourself when someone walks straight in front of your shot. Give us an aimless wander any day.

But, this time, because we were staying at Hotel Nena in Sultanahmet, we were on a mission to once more reacquaint ourselves with these places – because we could get there early!

The early bird… No crowds

First stop was Basilica Cistern.

We’d double-checked with the security guy the day before that it would be open. Yes, of course. Open every day.

Basilica Cistern isn’t run by the Culture & Tourism Ministry so they don’t have that day (usually Monday – the day we were visiting) where all is closed. Brilliant!

Bright & Early

So, it was up bright and early on the Monday morning. A huge Turkish breakfast to fuel us for our anticipated running of the gauntlet.

Then the short walk down the hill to the Basilica Cistern.

As we turned the corner to get to the entrance door. Wonder of wonders! Wide open doors and not a soul in sight!

Quick, quick, quick, let’s get in before the masses descend.

We paid our entrance fee and descended the 52 steps taking us below the ground and into the cistern.

This place has stood here since Justinian I, the Byzantine emperor from 527-565 AD.

When it came to water supplies, the Romans were pretty good at sourcing and directing it to those that needed it.

And the Basilica Cistern is an extra special example of this with its marble columns arranged symmetrically.

The Great Palace

The water stored in the Basilica Cistern was used to supply the Great Palace where the emperor resided, and then afterwards, by the Ottomans in Topkapı Palace for a short while.

As the Ottomans preferred running water to still water, they soon made alternative arrangements.

Yerebatan Sarnıcı was left to be forgotten.

And this is the part of the story that I love.

Just imagine if you were this person: The Basilica Cistern was left abandoned and forgotten until 1544-1550 when a Dutch traveller, Petrus Gyllius, rediscovered it and wrote about it in his travel memoirs.

He was told by residents in the area that they accessed water just by lowering buckets through their basements and pulling them back up filled with water.

Some residents even fished in the waters.

Miraculous Water

Petrus Gyllius clearly had a bit of the explorer’s streak about him because he wasn’t content with ‘miraculous water.’

He wanted to know where it was coming from and finally located an entrance. That must have been some sight!

The Basilica Cistern – the largest surviving cistern in Istanbul – was thus rediscovered and back on the map.

It wasn’t until 1987, however, thanks to a clean up by the Istanbul Metropolitan Municipality, that Istanbul’s visitors would be allowed to see what Petrus Gyllius had found over 400 years previously.

The Basilica Cistern Medusa Heads

People flock to the Basilica Cistern to see the Medusa heads

Because of the way the walkways in the Basilica Cistern have been arranged, if you can get there early enough, you are going to be ahead of everyone else.

And noooo, this is not a race or a competition or anything like that.

It’s just that if you are wandering ahead of everyone else, you get more of a chance to feel the whole atmosphere of the place.

The soft music. The dimly lit uplights throwing each marble column into full display. The carp swimming lazily in the waters below you, the water dripping from the arches above.

And yeah, okay, okay, you get first dibs on marvelling at, and photographing, the Basilica Cistern’s two great mysteries; the Medusa heads.


The Medusa heads are mysteries because no one is quite sure why they’re there.

Were they just seen as useful, practical bases for the columns which sit atop them?

Or was the head of Medusa chosen for a specific reason?

Why is one upside down and one on its side?

If just to see the Medusa heads, the Basilica Cistern is worth a visit

You can stand and ponder those questions whilst you gaze at the heads of Medusa sitting in the still waters. Theories abound.

Stone-carved Medusa heads were definitely used in this period to ward off evil spirits. The ancient theatre at Myra has one, for example. But these two famous faces of the Basilica Cistern can only leave scholars with guesses.

Don’t you just love a bit of ancient history, eh?

We spent around 30-40 minutes in the Basilica Cistern. And, of course, by that time, the crowds had started to stream in.

A few more photos as we made our way along the walkway towards the exit.

Then it was back to the glowing white of the souvenir shop and, eventually, the busy Istanbul streets of the 21st century.

Lol...I thought of the James Bond movie as well! I always loved going into this Cistern with visitors, especially when it was like 30+ degrees outside. It's a great way to cool off when it's hot outside! :)

Amazing how many people have said they love going to the Basilica Cistern in the summer to cool down, Joy. We're always in Istanbul in cooler weather so we'd never really thought about it. :) Must reacquaint ourselves with that James Bond film. ;)

I loved our visit to the Basilica Cistern . The atmosphere down there is so special, you end up whispering in order not to quench the magic drip-drop sound.

Yeah, it's definitely like that once you get further into the Basilica Cistern, Mette - these days, at the entrance, there's a photograph crew asking you if you'd like your photo taken dressed in Ottoman regalia. The more magical atmosphere happens once they are out of earshot. ;)

I love this place, it was such a great setting for a James Bond movie . I always imagine Sean Connery there when I visit.

Yeah, the Basilica Cistern is definitely a perfect setting for a James Bond film - as are many parts of Istanbul, come to think of it. :)
