It’s in a catherdral, so maybe the former? Most likely just a stairway to the upper gallaries and the clock-tower though.
This picture instantly brings to mind the poem, Antigonish:
Yesterday, upon the stair,
I met a man who wasn’t there!
He wasn’t there again today,
Oh how I wish he’d go away!”
When I came home last night at three,
The man was waiting there for me
But when I looked around the hall,
I couldn’t see him there at all!
Go away, go away, don’t you come back any more!
Go away, go away, and please don’t slam the door…
Last night I saw upon the stair,
A little man who wasn’t there,
He wasn’t there again today
Oh, how I wish he’d go away…
