Since it spans the whole floor space there must be a massive cavity in there
Others are correct, it’s the infrastructure for the building that in warmer countries is generally in a basement. Most Russian buildings do not have basements unless they are government because of the cost in excavating and stabilizing it. Instead buildings especially in the very cold areas of Russia are on stilts and entry points are elevated above the average snowfall.
That’s where .ml stores all the comments they find offensive.
Idk but I can tell you Moscow university was a tunnel / hallway behind those round windows. When I was there a quarter of them were broken and it was very exposed. Cold af
Ooh. Could you go behind those railings on the roof as well or were they just for show?
Probably, I was a kid exploring. The locked down areas weren’t locked down. This building is epic! There’s underground passages, and at the time I was there, dark abandoned underground Moria like spaces that went as far as the eye could see in the dark. It was in great disrepair, but, there was a full market on one of the basement levels. Basement floors the elevator didnt go. There was an attic space that was empty as far as the eye could see in the dark. Abandoned passages went between all the buildings on the university grounds. Ended up in one building from a passage where I could look out these glass doors to the outside, but, were locked. Was there in the mid 90s, no flashlight or cell phone so I explored as much as a kid dared to. Beautiful building, all sorts of hidden places.
