Holocaust-denial site Holohoax101 claims:
According to the USHMM website - "Between 1941 and 1944, Nazi German authorities deported millions of Jews from Germany, from occupied territories, and from the countries of many of its Axis allies to ghettos and to killing centers, often called extermination camps, where they were murdered in specially developed gassing facilities."
There are now only six alleged 'death camps', four were razed before the end of the war, and two, Auschwitz and Majdanek, are still standing.
The hoax gas chambers at Auschwitz and Majdanek are the only 'gas chambers' in existence.
Ignoring the claims of the chambers being hoaxes, are there only two remaining gas chambers from the Holocaust era?
