The entirety of Auschwitz includes the adjoining, larger Nazi
death camp, which you need to see by clicking on
Birkenau .
The original Auschwitz camp started by the Nazis was a
former Polish army barracks.  In the picture above you can
see that Auschwitz buildings are of brick, unlike the wooden
structures at Birkenau.  The curved poles were part of an
electrified barbed wire fence system.
The Auschwitz execution wall.  It is estimated that
the Nazis shot 70,000 prisoners here.
Entrance to an Auschwitz gas chamber.  I walked in
and also saw the ovens where bodies were burned.  
This was probably a reconstruction.
The Auschwitz Museum includes a series of huge chambers,
each displaying different personal items which the Nazis
looted from their victims.  Prisoners carried what little
they had with them, believing Nazi lies that they were going
to be relocated.  Instead they were executed, two to four
million murdered here at Auschwitz-Birkenau, at least half
of them Jewish.  For me, these endless galleries of
belongings from the dead were the most horrible things I
saw at Auschwitz.

Nazi loot included anything of possible value which could
be shipped back to Germany.  Above are pots and pans.  
There are also chambers full of shoes, luggage, Jewish
prayer shawls, and other similar items.   
Eyeglasses stolen by Nazis from their victims fill this chamber.
