Jewish World Review   

"BERLIN— (MCT) The shadows deepen and lengthen, memories grow dim, and some of the survivors of the tragedies of World War II scramble to preserve the recollections before the colors fade to gray.

"There's no shortage of ghosts prowling the cities and countryside of Europe. Remembrances of monstrous evil lie all about. None have tried harder than the progeny of the Germans who started it all to learn from the past, and recall without flinching the scourge and stain on history that is still unfathomable three-quarters of a century later." 

....

... "But none work with more dedication and enthusiasm for keeping the dark memories alive than a dwindling group of survivors of Hitler's death camps. Some of them are well into their 90s now, leaning on canes or advancing slowly across a room on a walker, talking to young people to whom World War II is as distant as the Hundred Years War."  Emphasis added, TD
....

... Very few prisoners survived the relentlessly efficient Nazi killing machine. Of 67 who survived at Treblinka, where 850,000 prisoners, nearly all Jews, were slain, only 2 survivors are alive today. Of the 250,000 scheduled for execution at Sobibor, only 50 survived and only 4 remain... 

Berlin Gestapo HQ before Hitler started the war

Memorial of the Holocaust: Topography of Terror  "As the “site of the perpetrators,” the "Topography of Terror" fulfills a special role among the many remembrance sites, monuments and museums in Berlin today that commemorate the era of National Socialism. Located in the center of the capital, it provides information at an authentic site about the headquarters of the National Socialist SS and police state and reveals the European dimensions of the Nazi reign of terror."

Gestapo HQ begins to have some consequences

New Third Reich Monument in Berlin: Revealing the Young Bureaucrats Behind the Nazi Terror     "Who exactly were the men who planned and administered the Nazi crimes? The new "Topography of Terror" documentation center opened on Thursday in Berlin at the site of the former Gestapo and SS headquarters.
"It reveals the faces of the almost unknown perpetrators of the Holocaust."

 exhibit in Berlin.

 

... "The area once housed not only Hitler's Gestapo secret police and its prison, but also the leadership of the SS, the Nazi party's paramilitary unit and the Reich Security Main Office. Nazi leaders such as Heinrich Himmler, Reinhard Heydrich and Adolf Eichmann all had offices on the street.

"The museum built in the middle of the remnants "leaves the city's scar visible," said the center's director, Andreas Nachama. The site is a few minutes' walk from the capital's Holocaust memorial, which opened in 2005, and the Jewish Museum."

A Woman Sent to be Gassed at Auschwitz

"From \"The Auschwitz Album\", the only photographic documentation of the entire extermination process at Auschwitz. An SS has just sent the woman with the infant to join those being sent to the crematoria; her hair is covered in the tradition of the Orthodox Jewish wife."

The "Gate of death" (part II)
This view is from inside the rail entrance to Birkenau. The building it passes through is the main SS guardhouse. Notice the windows in the tower. You may recall the scene in the film "Schindler's List", where the women are brought into Auschwitz at night with a large spotlight shining alongside the train. For a view of it from behind the light above the ramp see [link]. The object at the bottom of the frame, near the track is a rail switch.
