Thanks you to all the entrants, some interesting interpretations. I'd guess not all of us even want to appreciate Industrial architecture. IT even sounds horrible. It is nevertheless an unavoidable part of our real world. So, thanks that you all took out the time to capture something.
Having looked at the images, and the criteria 1) it must be industrial and 2) there must be some lements of architecture.
On those two criteria, the image of Tsakastaka is the winner. There's even some nice lines there. And despite that I think its more of a market like stall, the power lines give it its industrial setting.
So well Done Tsakatsaka.
