If you look between the pillars, there's a blue color, which seems to be water, and there's what seems like it may be steam coming off of it on the right side.
That sucks though cause if it was Newcastle then that structure would be the Theatre Royal, which would explain the Dark type gym on top of it. But if it's a roman bath, I don't get how a Dark type gym would tie into things at all.
