The Colours of Ostrava venue

Colours of Ostrava music festival is held in a massive former industrial complex of some sort (yesterday I posted some photos from this year's festival). It seems like the type of place that processed or produced a variety of things. Perhaps heavy metals of some sort. Maybe chemicals. Whatever its previous existence was, it now is the location for a huge music festival. I'm sure its been cleaned up a lot since its active dates, but I still wouldn't want to spend too much time there (or lick the walls).

This is a Lubitel shot I took of a small section of it:
