The Brutal T.0.rtures Inside Block 11 in Auschwitz

There is a hierarchy in suffering. Even in the most terrible place on earth, there is always a corner that is worse than everything else. If Auschwitz was the “anus of the world,” as some survivors described it, then Block 11 was its black beating heart. For the 150,000 prisoners who barely survived in the main camp of Auschwitz, death was a constant companion.

It was in the electrified fences, in typhus, in the hunger that gnawed at the bones, and in the greasy smoke of the crematoria. But there was a different fear. A sharp, paralyzing terror that silenced the barracks at night. It was not the fear of dying, but the fear of being sent there—to the red brick building located in the camp’s southeast corner.

The building that always had its shutters drawn. The building from which no one returned the same person, if they returned at all. Block 11. The prison within the prison. While chaos ruled the rest of the camp—the Kapos’s screams and the barking of dogs—Block 11 was wrapped in a sepulchral silence. An artificial, heavy silence designed to amplify every footstep, every bolt, every groan.

It was the Gestapo’s private domain, a laboratory of cruelty, where the concentration camp’s normal rules—”work until you die”—were suspended. You did not go there to work. You went there to suffer. There, the gas that would kill millions was tested for the first time. There, the art of killing a man without touching him was perfected using only confinement and darkness.

Today we are going to cross that wooden door. We are going to descend the stone stairs that thousands went down and very few ever climbed back up. We are going to examine the records, the graffiti scratched with fingernails into plaster walls, and the testimonies of the few who escaped the clutches of Commander Grabner.

Forget what you think you know about the Holocaust. This is not the story of Birkenau’s industrial machinery. This is an intimate, claustrophobic, brutal story. This is the story of what happens when a human being decides to become voluntarily and meticulously a demon. Welcome to the block of death. Chronicle of eternal darkness.

The Geography of Horror

To understand the horror of Block 11, we first need to understand its geography. Auschwitz I, the base camp, was a former Polish army barracks. Solid red brick buildings, two or three stories tall, lined up in orderly rows. Seen from the air, they look harmless, almost institutional, like a university or an old hospital.

But Block 11 had architectural features that gave it away. If you walked along the camp’s main street, you could feel the temperature drop as you neared the right-hand corner. Block 11 was isolated from the rest by a stone and wood fence that connected to Block 10, the block of medical experiments. Between the two buildings, a closed courtyard formed, invisible from the outside—a dead-end alley paved with gravel and sand.

But the most unsettling thing was the windows. Unlike the other blocks, the basement windows of Block 11 were covered by concrete baskets or external wooden boxes that kept light from entering and blocked the view. From the outside, the building looked blind. From the inside, it was a living tomb. The block’s official function was to serve as the Commandantur Arrest, the camp’s jail.

It was the place of punishment for prisoners who broke the rules: attempting to escape, stealing food, sabotaging work, or simply looking at an SS officer the wrong way. But it also served as a pre-trial prison for Polish civilians from the Silesia region suspected of belonging to the resistance, who were brought in from outside to be interrogated by the Gestapo.

A prisoner’s journey to Block 11 almost always began the same way, with a shouted order on the roll call square: “Heftling 3,451. Report to the gate.”

The prisoner knew what that meant. His comrades instinctively stepped aside as if the condemned man carried a contagious disease. No one said goodbye. No one looked him in the eyes. He was a dead man walking. Upon reaching the door of Block 11, the atmosphere changed dramatically. The SS guard at the entrance, the Blockführer, did not shout like the others there. Everything was procedure—cold, efficient bureaucracy.

The Kingdom of Maximleian Grabner

The entry was recorded in a ledger in impeccable Gothic handwriting. Name, number, reason for arrest. Often the reason was simply “Bunker,” a word that in Auschwitz was synonymous with indefinite torture. The ground floor of Block 11 looked at first glance like a normal administrative office. There were long corridors, waxed floors that shone under electric light, and numbered doors.

It smelled of floor wax, stale tobacco, and leather. But there was an underlying smell, metallic and sweet, that no cleaning product could hide. It was the smell of concentrated fear and old blood. To the right of the main corridor was the guard room. Here, the men of the political section—the camp’s feared Gestapo headed by Maximleian Grabner—relaxed.

They drank schnaps, played cards, and listened to the radio while only a few meters away, men and women were being destroyed. Grabner, a man with a bovine face and an arrogant stare, was the absolute master of this domain. He boasted that he could decide the life or death of any prisoner without even consulting the camp commandant, Rudolf Höss.

For Grabner, Block 11 was his private kingdom. But the true bureaucratic terror unfolded in the improvised courtroom, the infamous Polizeistandgericht or summary police court. Every few weeks, Gestapo dignitaries arrived from the city of Katowice. They sat at a long table covered with a green cloth in one of the rooms on the ground floor. It looked like a court.

There was a judge, a clerk, minutes, seals—but it was a macabre farce. Civilian prisoners, men and women brought from the prisons of Mysłowice or Katowice, waited in the corridor, faces to the wall, unable to move. If they turned their heads, they received a rifle butt blow to the back of the neck. One by one, they were pushed into the room.

The trial lasted on average between 60 seconds and 3 minutes. The Gestapo officer read out the name and the charge: “Do you admit to listening to foreign radio? Do you admit to giving bread to partisans?”

The answer did not matter. Most of the time, the prisoner did not even have time to open his mouth. The judge glanced at the file, looked at the prisoner with boredom, and pronounced the sentence. Almost always the same. The judge simply made a gesture with his hand or marked a cross on the paper—a red cross. That cross meant “Tod”—death.

If the prisoner was lucky, he was sentenced to the concentration camp, which gave him a life expectancy of 3 months. But most of those who entered the courtroom of Block 11 walked out with an immediate death sentence. What is chilling is not the injustice, but the administrative normality of the process. Between sentences, SS officers joked, passed cigarettes around, talked about their vacations, or the quality of the food in the officer’s mess.

Meanwhile, a human being trembled in front of them, wetting himself with terror, knowing his life ended right there. Once the sentence was handed down, the condemned were not taken back to their cells. They were taken to the washrooms on the ground floor. There, they were ordered to undress completely, men and women together.

The Logic of Dehumanization

Shame was the first tool of dehumanization before the end. They had to leave their clothes neatly folded. The Nazis hated disorder, even in the middle of a massacre. Naked, shivering from cold and fear, the victims waited, sometimes for hours, listening to the shots coming from the courtyard, knowing each detonation meant the line was moving forward and their turn was closer.

But before we reach the Black Wall or the basement bunkers, we must talk about another method of torture that took place on the upper floors. One that is often overlooked: the “Post” or hanging from the stake in the attic of Block 11. Under the wooden roof beams, the SS installed hooks in the rafters. It was a punishment reserved for camp prisoners who had committed minor infractions, such as trying to steal an extra piece of bread.

The punishment consisted of tying the prisoner’s hands behind his back with a chain. Then he was lifted onto a stool and the chain was hooked to the ceiling. With a kick, the guard knocked the stool away. The weight of the body fell entirely on the shoulder joints, rotated backward into an unnatural position.

The pain was blinding, instant. The tendons stretched to their limit. The shoulders dislocated from their sockets with a dry crack. The prisoner hung like that for an hour, sometimes two. If he passed out from pain, a bucket of cold water was thrown over him to wake him up so he could keep suffering.

The diabolical aspect of this punishment was not only the acute pain in the moment, but the aftermath. When they were lowered, the prisoner’s arms were useless. They could not move them. They could not lift a shovel or a wheelbarrow. And in Auschwitz, if you could not work, you went to the gas. The prisoner who survived the stake torture in Block 11 knew he had been sentenced to a delayed death.

He returned to his barracks with his arms hanging limp at his sides, unable to eat his soup without help, hoping the Capo would not notice or waiting for the next selection by Dr. Mengele. It was a torture designed to turn a healthy man into a disposable object in 60 minutes. But let us leave the upper floors behind.

The Black Wall: The Assembly Line of Death

The true notoriety of Block 11, the reason its name was whispered with dread from Norway to Greece, lay in what happened in the courtyard and, above all, underground. The courtyard between Blocks 10 and 11 was enclosed by high brick walls. The windows of Block 10, where the experiments took place, were boarded up with wooden planks, but the prisoners inside could hear.

They heard everything. At the end of the courtyard stood a simple structure, almost banal: a wall built from black-painted logs covered with a layer of cork and sound-absorbing material. The Schwarze Wand—The Black Wall. The ground in front of it was not earth, but sand. Sand to absorb blood. Sand that had to be changed constantly because it turned into sticky red mud.

Execution at the Black Wall was not a military firing squad. It was slaughterhouse style: clinical and dirty. The main executioner was not always a high-ranking officer. Often it was Rapportführer Palitzsch, described by survivors as the embodiment of emotionless sadism. Palitzsch had a particular technique.

He used a small-caliber rifle, a 6mm Flobert, or sometimes a Walther P38 pistol. He did not want larger calibers because they made too much noise and shattered the head too violently, splattering his uniform. The condemned, naked, were brought out two at a time by the corpse carriers—Jewish prisoners from the Sonderkommando assigned to Block 11.

They were made to run. Speed was essential to prevent resistance. They were grabbed by the arms and dragged to the wall. “Face the wall!” they shouted.

The victim stood trembling, staring at the black wood stained with dried and fresh blood. Palitzsch approached from behind, placed the barrel at the base of the skull, right where it meets the neck, and pulled the trigger. A dry crack. The body pitched forward or collapsed to its knees. Immediately, the corpse carriers ran in, grabbed the body by hands and feet, and threw it onto a pile in the corner of the courtyard.

Meanwhile, the next pair of victims was already being dragged out through the door. It was an assembly line. It is said that Palitzsch, on a day of “good work,” could personally execute 300 people without rest. He stopped only to reload and light a cigarette. There are testimonies that on occasion when transports arrived with children, Palitzsch let the children play in the courtyard with a ball for a moment before calling them one by one to shoot them.

The prisoners in Block 10, spying through the cracks in the planks, counted the shots. They kept track of the dead. Sometimes blood flowed in such quantity that it formed a small stream that crossed the courtyard and seeped out under the door toward the camp’s main street. The SS had to build a special drain to prevent the blood from exposing the massacre in broad daylight.

The Basement: Engineering of Suffering

But the Black Wall was, in a sense, a quick death—a mercy. What awaited in the basement of Block 11 was far worse than death. It was the dissolution of the human mind. The stairs leading down are worn smooth by the guards’ boots and the prisoners’ bare feet. As you descend, the light changes. The air becomes damp and cold.

Down here, the sounds of the camp do not reach. It is a sealed world. The basement had 28 cells, but not all were the same. There were three kinds of hell down here: the normal cells; the dark cells with no light at all, where prisoners lost all sense of time; and finally, the standing cells—the Stehzellen.

This is the point where Nazi cruelty crosses the line of torture and enters the realm of experimental engineering of suffering. The standing cells were not cells. They were niches, vertical holes in the wall. Imagine a space 90 by 90 cm—a square less than a meter across. Now imagine four adult men being forced into that space.

They entered through a small door at floor level, like the door of a dog oven, and had to crawl inside. Once inside, they had to stand. Four men pressed shoulder to shoulder, back to chest, breathing each other’s stale breath. The door shut. Total darkness. How do you survive a night like that? You cannot sit. You cannot kneel.

If you fall asleep and your knees buckle, your weight collapses onto the others, who shove and hit you to make you stand again because they are suffocating. The air ran out quickly. There was only a small 5cm opening at the top for ventilation. The men gasped, fighting for a thread of oxygen. Body heat drove the temperature up until the niche became a steam bath of sweat and urine.

Because there was no bucket, they had to urinate and defecate on themselves standing, smearing their companions. This was not a punishment for an hour. It was a punishment for the entire night—10 hours on their feet. And at dawn, the door opened. The men fell out like stiff blocks of wood, but they were not allowed to rest.

They had to go to work—11 hours of forced labor digging trenches. And when they returned at night, back again to the standing cell. No one lasted more than a few weeks. Legs swelled until they seemed ready to burst. Massive edema. Kidneys failed. Madness took hold. Often, when guards opened the door in the morning, one of the four was already dead.

But he was still standing, held upright by the pressure of the living bodies who had spent the last hours clinging to a corpse that was warm, then cold, in absolute darkness. If the standing cells were torture designed to break the body through exhaustion, the neighboring cells had a different purpose: to break the mind through absolute deprivation.

The Starvation Cells and Maximilian Kolbe

Along the damp basement corridor were the starvation cells. Here, the death sentence was not carried out with a bullet or a rope. It was carried out with time. Commander Karl Fritzsch, a man with a particular sadistic imagination, used these cells to punish escapes. The rule was simple: for every prisoner who escaped and was not recovered within 24 hours, 10 of his barrack-mates were selected to die of starvation.

To die of hunger and thirst in a concrete cell is not a peaceful death. It is a ferocious biological battle. The human body, deprived of water, begins to delirium from the third day. The tongue swells until it no longer fits in the mouth. In desperation, prisoners drank their own urine or licked condensation from the walls. SS guards did not hear silence; they heard howling—grown men reduced to caged animals.

It was in one of these cells, number 18, that one of the most famous events in the history of Auschwitz occurred. July 1941, a prisoner has escaped. The roll call lasts for hours. In the end, the fugitive does not appear. Karl Fritzsch walks along the ranks and points to 10 men. One of them, Franciszek Gajowniczek, breaks down crying: “My wife, my children.”

Then a small man steps forward—Maximilian Kolbe, a Catholic priest. He does not plead for mercy. He asks for an exchange. He asks to take the place of the family man. The 10 men were stripped and thrown into the darkness of cell 18. Normally, the bunker became a madhouse of cannibalism and violence within days. But the bunker Jacob reported something unheard of.

From cell 18 came no screams or curses. There were hymns. Kolbe had organized the dying men. They prayed. They sang. He turned the torture chamber into a kind of sacred crypt. But biology is relentless. One by one, the men died. After 2 weeks, only four were still alive. Kolbe was the only one who remained conscious, staring at the door with an unnatural calm.

For the SS, this was unacceptable. On August 14th, they brought in Hans Bock, who carried a syringe filled with phenol (carbolic acid). A phenol injection is an atrocious death, injected directly into the left ventricle of the heart. According to the block caretaker, Kolbe did not struggle. He extended his skeletal left arm toward the executioner. It was the end of a man, but the beginning of a legend.

The Birth of Cyclone B

The basement of Block 11 holds an even darker secret—one that would change the history of humanity and turn it into an industrial nightmare. It was here, not in Birkenau, that the Holocaust as we know it was born. Until the summer of 1941, the Nazis executed their victims primarily through mass shootings, but this method was slow and shattered the morale of the German men.

In late August or early September 1941, Karl Fritzsch decided to carry out an improvised experiment. He had noticed that the camp’s disinfection company used a crystalline pesticide called Zyklon B to kill lice. If it killed insects, Fritzsch reasoned, it would kill human parasites. They chose the basement of Block 11 as a laboratory.

They selected 600 Soviet prisoners of war and about 250 sick Polish prisoners. They shoved them down into the basement cells. The procedure was crude. SS men covered the basement windows with earth and rubble. An officer, protected by a gas mask, opened one of the window vents and poured the purple granules over the heads of the men packed below.

What happened inside was a slow agony. The gas needs heat to evaporate; without enough heat, the gas was released very slowly. The prisoners did not die immediately. They coughed, choked, and pounded on the doors. The experiment dragged through the night. The next day, many prisoners were still alive, crawling among corpses and vomit.

The SS, furious at the inefficiency, shut the doors again, sealed the cracks more tightly, and poured in more Zyklon B. It took two full days to silence the basement. When they finally ventilated the gas, a special group had to disentangle the mass of 850 corpses. This event was the turning point. Fritzsch reported to Höss: “It works.”

From that moment on, Auschwitz ceased to be only a brutal concentration camp and became a factory of death. Block 11 had given birth to the monster.

The Silent Resistance: Mala and Edek

We cannot speak of Block 11 without mentioning the invisible figures who lived in its shadows—the block workers. One of the most harrowing testimonies comes from survivors’ memoirs about Jakob, a Jewish cleaner. He had to clean blood from the floor after Gestapo interrogations and carry the bodies from the wall. If the SS found a stain of dried blood, the cleaner took the victim’s place.

Block 11 had its own accounting system, the “Bunker Book.” Every entry, every death was recorded meticulously. If a prisoner died during excessive torture, the SS doctor signed a false death certificate: “heart failure” or “pneumonia.” But despite this, acts of defiant love and resistance still occurred.

In the summer of 1944, two prisoners planned the impossible. He was Edek Galiński, a Pole. She was Mala Zimetbaum, a brilliant Belgian Jew. They fell in love in the place where love was forbidden. They managed to escape for two weeks before being captured at the border and brought back to Block 11.

The Gestapo wanted names. Edek was hung from the stake; Mala was tortured with ferocity. But neither spoke. Even in separate cells, they found ways to communicate. Edek carved their names into the wall of his cell: “Mala and Edek.” Through compassionate prisoners, they exchanged small scraps of paper. Edek sang Italian songs from his window so Mala would know he was still alive.

The SS wanted a spectacle for their execution. Edek was led to the gallows, but he did not give them the pleasure of killing him. Before the executioner read the sentence, Edek shouted: “Long live Poland!”

He kicked the stool away himself. Mala, in the women’s camp, did something even more shocking. She pulled out a razor blade she had hidden in her hair and slit the veins in her wrist in front of everyone. When an SS officer ran toward her, Mala, with her bloodied hand, slapped him across the face with all her strength. She died on the way to the crematorium, having won her last battle.

Conclusion: The Legacy of Block 11

As 1945 arrived, the Gestapo tried to erase their tracks. They burned the bunker files and destroyed the Black Wall. But they did not have time to destroy the building. When the last prisoners left on the death marches, Block 11 stood empty. Today, it still stands as part of the Auschwitz-Birkenau State Museum.

It is the one place most visitors describe as impossible to endure. Despite the years, the basement still smells of cold, damp, and something indefinable that raises the hair on your skin. If you light the walls carefully, you will see the final legacy: thousands of marks, names, and crosses carved with fingernails into the plaster. “Joseph, goodbye. God, help me.”

They are screams frozen in time—the forensic proof that human beings were there who, in their last moments, only wanted to leave evidence that they existed. Block 11 was the most intimate and cruel face of the Holocaust. It is an eternal warning that civilization and human rights are fragile, and that an ideology of hate is enough to turn any basement into the antichamber of hell.

The doors are open now, but for the thousands who entered and never came out, Block 11 remains—and will always remain—the end of the world.
