These pictures are not for the faint of heart, but they MUST be shown.
This is the park which used to be the site of Vienna Gestapo Headquarters.
A monument is there now.
They have planted some very tough plants in this park. It is not the kind of place where you feel comfortable, you can't lie down on the nettles and thistles and crab grass they intentionally grow there. Not sure if I have much interest in the "plank", but somebody made the effort.
And I am making the effort to show the monuments.
