did you see...!?

I discovered these two frogs in a decommissioned waste water treatment plant which was opened to the people as some sort of industrial memorial monument. You can walk around in the old basins, some of them filled with some water and a labyrinth of stones you can walk on, others filled with a future forest, in one there is even a playground. It is a very special place with many graffities and full of life. What a difference to when it was a waste water treatment plant...!
