Need help with identifying an interior.

Either in my dream, or some movie I saw over a decade ago, there's an interior of a building that goes something like this:
It's a grand staircase, in this color/stylе:

But it's the same height as the grand staircase in grand central station:

however, it's way less curvy than the grand central staircase, it's just a really wide straight line iirc. And then there's a 90 degree turn from the staircase to a really long walkway. Everything is so huge, the humans look tiny compared to everything.

Thanks!
