Vatican - Momo staircase

The spiral staircase built by Giuseppe Momo is called the Momo Staircase or the Snail Staircase. It is made out of two wrought iron stairways, with one going up and one going down. It is formatted in the curve of a double helix, which wasn’t Momo’s original intention. It just so happened that years later, the helix would become a recognisable symbol of life.
