The Scala Santa Devotion

History of this devotion
The original Scala Santa, also known as "Holy Stairway" is the staircase which Jesus ascended during His Passion while proceeding to Pilate's pretorium.
By the Saviour's footsteps, that staircase which is still in existence today, was sanctified. It continues to be venerated in Rome, in the Basilica of St. John Lateran.
During the last century, it became the custom in many parts of the Catholic Church to erect staircases similar to the Scala Santa in Rome. The first Scala Santa to be built in America in 1891 is found at Sainte Anne de Beaupré, Québec, Canada. (26 miles East of Québec City.) Like those of Rome, the Stairs, consisting of 29 steps, are inside, starting on the second floor.
Indulgences
On November 13, 1893, Pope Leo XIII granted that the faithful who ascend the steps of the Scala Santa on their knees, with a contrite heart, praying and meditating on Our Lord's Passion, may gain an indulgence of three hundred days for each step. This indulgence is applicable towards the souls in Purgatory.
While no special prayer is obligatory, as a convenience to pilgrims, a short prayer is given here for each of the 28 steps. These short prayers are worthy of veneration, because they were composed and published in Rome for the use of pilgrims to the original Scala Santa.
Prepatory Prayer
(Note: While this prayer is not part of the original Scala Santa devotion, it is an introduction to the Sacred Stairs which begin on the first straight step.
O merciful Jesus!
For the salvation of mankind, You did submit to the suffering of the scourging and crowning with thorns; You did allow Yourself to be dragged by impious hands on these stairs to be led before Pilate. I desire to venerate with deep respect the bloodstained traces of Your Divine feet, and I humbly beg You, by the merits of Your Passion, to grant, that I may one day ascend to the Throne of Glory, where You live and reign with the Father and the Holy Ghost forever and ever.
Amen.
Prayer for each of the 28 steps
(Note: A Hail Mary and an invocation to your Patron Saint may be added to each step.)
