Visited with Andy Skotsko. I can't find much information on the history of the building unfortunately, but suffice to say this is a stunning example of Soviet brutalism, 70's I'm guessing, and still in fantastic condition by the looks of things.
We didn't get far inside as while closed, the building still has security. An tour-explore was requested (and considered by the seems of things) but didn't happen. It was possible to get a few shots of the interior through the glass facades.
Main exterior via the walkways.

Would have been great to have gotten inside, might try this one again.
