Introduction to the gas chamber: In the middle of the gas chamber of Incinerator No. 1, flowers presented by mourners are placed. The SS once massacred Jews here. Now it is a place where people express their grief. The original layout looks solemn and solemn. A sign next to it simply reads in Polish, English and Hebrew "You are at a place where the SS massacred thousands of civilians, please remain silent: remember their pain and remember them silently".
