Six million people, mostly Jewish, were murdered by the Nazis.

More than a 1,000,000 off, um in this camp, while 75 years ago to date the Soviet army liberated Auschwitz, and it came to symbolize the horrors of the Nazi regime.

Today, ceremony had at its heart the survivors who urged the world never to forget the suffering here.

Our world affairs editor, John Simpson, was watching.

Each anniversary.

There are fewer survivors.

Yet even after 75 years, there are still thousands off the left.

Soon after dawn today, Igor Mallet, ski prisoner number 188005 took part in a ceremony at the wall where tens of thousands were shot.

Nowadays, Auschwitz is protected and restored so the world won't forget the terrible things that happened here.

The infamous gateway to Auschwitz was covered over with a vast warning to protect the guests from the bitter cold of southern Poland royalty world politicians, though no British ministers among them religious leaders, but above all the survivors themselves.

Many proudly wore the blue and white stripes of the pajamas, which the Auschwitz inmates were forced to wear rows upon rows of seemingly unremarkable elderly people who are among the last living witnesses of unimaginable cruelty.

The worst crime in human history.

Here in this great factory of death violence see the American in Auschwitz Birkenau.

I remember naked women driven in trucks from the barracks to the gas chamber.

I can hear them screaming.

I can hear it in my subconscious When I remember those events.

As another speaker noted, nothing was done to stop the slaughter.

Jack sharpen pork itch.

Maybe I would like to cry, because only with tears I can tell you about this past.

I hope you will all try to preserve the memory of this place on other sites where innocent people died.

I hope you'll bear this responsibility so that this terrible thing will never happen again.

There were thousands of Nazi concentration camps, but Auschwitz was by far the worst.

1.3 million people were brought here on 1.1 million off them died.

The plan was to use industrial methods toe wipe out the Jewish people.

Understandably, many ex prisoners are reluctant to come back, among them higher Fresh, who lives in Israel.

She was sent to Auschwitz from Hungary at the age of 20 with her parents and sister.

Now, though, she's decided she's got to show her daughter what it was like with 70 others.

She was jammed into a railway truck like this for three days, with no food or water.

Her mother and sister survived with her.

Her father was sent directly to the gas chamber.

Her father, they took her father, he said.

He said that Father Waas not right side and that's it.

They didn't see him anymore.

Tonight, after the gathering at the Auschwitz gateway, the guests went out and walked along the railway line, where doctor Joseph Mengele's, the so called Angel of Death, had once decided which of the new arrivals should live or die.

They place candles up the monument.

This terrible death camp was planned.

Toe wipe out.

The Jewish people failed utterly.

Auschwitz well Among those who didn't banish to survive their time at Auschwitz was Anita, Alaska Val Fish, who's now 94 she arrived here Fear, fearing the worst.

But she escaped death by saying that she was a musician.

Hand in this place of mass murder, torture and starvation was signed up to play in the women's orchestra.

I went to speak to the woman who came to be known as the cellist of Auschwitz at her home in north London.

That's a funny picture off me.

Sitting on the floor with Children's room in the Komen.

I was scraping the thing, and I think my parents must have seen that and said, I think she wants to play the cello.

Anita, Alaska Val Fish arrived in Auschwitz in 1943 fearing he was destined for the gas chamber prisoner sit and do the work, shaving your head into doing a number on your arm.

So this girl asked me, Where do you come from?

And what did you do before the war?

And like an idiot, I said the I used to play the cello.

She said, Fantastic.

You would be saved our job.

Voss every morning to sit at the gate and play marches for all the workers who worked out into the factory and in the evening we had to go against it.

Outside the camp, play marches again for the people who came back and he survived like we knew very well.

As long as they want music, we will exist.

The cello saved my life.

How on earth did you endure that environment?

You lived from one day to the other.

Today I'm alive tomorrow.

Probably not.

So that's what life was.

Very, very short notice.

Yeah.

After the horrors of the war, her love of music dominated her life.

She helped found the English Chamber Orchestra trying to put the past behind her.

What has been the effect on your life afterwards, of being a survivor?

Well, I think I have never lost my sense of appreciation that I am alive and I have a house and I have enough food.

And, yeah, I've never lost being grateful somehow and appreciate what I've got.

But the trauma didn't end.

Her daughter, Meyer says she's been profoundly affected by being the child of a Holocaust survivor.

Without a doubt, I absorbed unconsciously all of the trauma that my mother tried so hard to contain.

So my parents, my mother, I really could not understand why if this is absolutely literal, if I wasn't about to be killed and if I wasn't starving, what was my problem?

Have you ever been bitter?

I'm not bitter.

I'm I'm sad that really nothing seems to have changed.

People kill each other as we're speaking now, why, boy, there was the extraordinary Anita Alaska Val fish there, or 3/4 of a century has passed since this camp was liberated.

But there remains inevitably an eerie, haunting chill to this place.

Many of the old buildings are still here, including those where so many met their deaths.

Today's event is possibly the last major gathering off the survivors.

Last time, five years ago, there were 300 who came this time just over 200.

Their message In a world where anti Semitism is on the rise, the monstrous crimes committed here must never be forgotten with that, it's back to you, Clive Rita.

Thank you.
