Construction of a stronger and more massive bell tower for the monastery to replace the one destroyed during the last civil strife with a neighboring lord was well underway when the old Monk visited the site. The Abbot showed the Monk the drawings and model for the three-bell tower. The Monk was impressed until he stood where the bell chamber would be and saw the spiral staircase in this medieval bell tower running the wrong direction (counterclockwise).
"The staircase direction must be changed," said the Old Monk. The Abbot looked at the staircase and agreed. Why?
