Ostrava, Czech Republic, 7/2017 Abandoned oil refinery. It is very polluted spot. Water is black. It is a mixture of water and some chemical waste mess. Density of water - not sure - but looks like oil. Smells like asphalt when new roads are laid. These days area is being cleaned. After 20 years of inactivity. We could hear sounds of chain saws as workers were cutting bushes and trees. Green jungle is being replaced. Almost unreal and unbelievable. But is is true. © Pavel P.
