The (, ) 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 (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" (), which was the personal chapel of the early Popes. According to Roman Catholic 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. In the Middle Ages they were known as Scala Pilati, (the Stairs of Pilate). For centuries, the Scala Sancta has attracted Christian pilgrims who wish to honour the Passion of Jesus Christ. Since the early 1700s, the Holy Stairs have been encased in wood for protection, but were briefly exposed in 2019 following restoration work. History According to Roman Catholic 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. Medieval legends claim that Saint Helena, mother of Emperor Constantine the Great, brought the Holy Stairs from Jerusalem to Rome circa AD 326. In the Middle Ages, they were known as "Scala Pilati" ("Stairs of Pilate"). From old plans it appears that they led to a corridor of the Lateran Palace, near the Chapel of Saint Sylvester, and were covered with a special roof. In 1589, Pope Sixtus V had the Papal Lateran Palace, then in ruins, demolished to make way for the construction of a new one. He ordered the Holy Stairs be reconstructed in their present location, before the Sancta Sanctorum (Holy of Holies), named for the many precious relics preserved there. The chapel also houses an icon of Christ Pantocrator, known as the "Uronica", that was supposedly begun by Saint Luke and finished by an angel.
