It was erected in 1772 as reproduction of the Scala Sancta in Rome. Pope Clement XIV gave it to the Confraternity of Stigmata of St. Francis. During the Easter period until Pentecost, the plenary indulgence was conceded for climbing and praying the stairs on the knees, ladies are requested to cover their head. Paintings along the stairs represent the Passion of the Christ and pilgrims, climbing the stairs can experience symbolically the Christ suffering.
The last step leads to the Sancta Sanctorum, where is located the altar of Cristo Salvator Mundi. Here pilgrims can be delivered from sins. Once purified the soul, the devotees climb down the stairs with joyful resurrection images and smiling angels on the roof.
The Scala Sancta is located in the main square of Campli, behind Palace Farnese. It is composed of 28 oak-wood stairs and according to Roman Catholic tradition, the Holy Stairs are the steps leading up to the praetorium of Pontius Pilate in Jerusalem on which Jesus Christ stepped on his way to trial during his Passion.
