Holy Stairs

The Scala Sancta are a set of 28 white marble steps located in an edifice on extraterritorial property of the Holy See in Rome, Italy proximate to the Archbasilica of Saint John in Laterano. Officially, the edifice is titled the Pontifical Sanctuary of the Holy Stairs, and incorporates part of the old Papal Lateran Palace. Replica stairs flank the original staircase, which may only be climbed on one's knees. The Holy Stairs lead to the Church of Saint Lawrence in Palatio ad Sancta Sanctorum or simply the "Sancta Sanctorum", which was the personal chapel of the early Popes.

According to Catholic Church tradition, the Holy Stairs were 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. The Stairs reputedly were brought to Rome by Saint Helena in the fourth century.
