I can't see the staircase in this photo, though I think I recognize the arches... do you have any photos of the stairs at the left arch? Also, how did you get this picture, did you take it yourself? I know not just anyone can go in there so I am curious.
Yes, I took the photo.It is open to the public; it is the exit from the Sistine Chapel to St. Peter's Basilica when in the Vatican Museums.I have no other photos of the stairs.
what type of column order is that?
well the column doesn't really have a typeit's baroque , so they use volutes for everything :)by the way i didn't know it was publicit's build as a passage for the pope and cardinals
