Rusted...

metal storage silo at the old, abandoned grain mill.

It's a favorite destination for a dog walk..the windows are all busted, it's home to hundreds of pigeons and the walls are covered in graffiti. A bit spooky but very cool.

Edit: cropped it closer, diddled a little with curves
Edit 2 (last attempt to make it interesting): grain filter multiplied, rotated, overlayed
