Standing at the lip of the lava lake you can see why the locals see this as "the gatewaytohell", as the incandescent bubbling lava lake hisses like some badly burned porridge cauldron, overturning and occasionally belching molten lava.
The Czech ghetto was still a gatewaytohell but because it was less brutal and squalid than the others it also came to play a role in one of the most extraordinary of all the German propaganda operations of World War II.
