Here are other new photos of an earlier set of photos from an abandoned factory in Casteliorentino in Italy. The construction of concrete is really impressive, whereas theare are two of them: one arc-type building and another cubical one.
This 3D GRID is a skeleton of an abandoned factory. I don’t know what huhge construction this was for, but it’s spectacular to see and take photos. Have a look to the complete series (part 1) here.
