The stairs seem to go on forever. After several twists and turns and dusty landings, you arrive on what seems to be two floors up.
It appears the second floor was once accessible to the public. Indeed, the central atrium looks into this floor - well, it did, but a newly installed fake roof is attached in the centre in its place. Around you is a massive empty space, with areas enclosed by walls jutting out. Judging by the flooring and the wallpapering, the non-enclosed areas were once rooms as well, and a hallway wrapped around the atrium. But that is all gone now.
The only major thing that remains is three doors on the walled areas - presumably they access them. Two are still labelled as "staff area" - another reminder of the space's former nature - and one as a bathroom. Apart from that, there's a bunch of folding chairs and tables scattered around the remaining space. Nothing is on them.
