Metal Tipi

It looks like the apartment of some cyber native americans, doesn't it?
Actually it was the construction site of a wastewater treatment plant.
I couldn't resist sneaking in and exploring the inside of the tower. It came to my mind that I'm probably one of the last humans to be inside it. As soon as the plant starts working the tower will be filled with stinking fluid.
Anyway - it felt great to be in a place I'll never see again.
