The miraculous stairs

One of our stops in Santa Fe was at an old church with a set of spiral stairs called the miraculous stairs.
Here is the story in a nutshell.
A church was built in the town of Santa Fe in the usual manor. And as was customary they didn't leave enough room for a staircase up to the choir loft. After consulting with many craftsman the best solution was a ladder.
So this group of nuns prayed for nine days for someone to help them. On the ninth day an unknown carpenter shows up at their door and tells them he can build something.
After a number of months the spiral staircase was complete and the carpenter disappears without a name or being paid.
It was decided that it was a Saint who was the mystery guest.
Whatever the situation the staircase is a beautiful piece of art.
Look it up.
