StoryThe Scala Sancta (English: Holy Stairs, Italian: Scala Santa) are a set of 28 white marble steps that are Roman Catholic relics 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 (Pontificio Santuario della Scala Santa), 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 (Chiesa di San Lorenzo in Palatio ad Sancta Sanctorum) or simply the 'Sancta Sanctorum' (English: Holy of Holies), which was the personal chapel of the early Popes.
