Peeping pipes

Today I "completed" one target of my to-be-photographed list. I took a walk around to local old cement factory, which I have passed many times by train and found it very interesting structure. Lots of pipes, chalice dust all around huge buildings reaching the sky. Now my hunger get even bigger and I do want to get in to that area...

This is only part of the whole structure. Behind the building is huge chalice pit-mine of 150 m deep at the moment.
