Opposite the Basilica of San Giovanni in Laterano (St. John Lateran) in Rome, the Holy Stairs are said to be those walked up by Christ, as he was condemned to death by crucifixion. The Holy Stairs were brought back from the Holy Land by St. Helena, the mother of Constantine the Great. The stairs are marble, but today are covered in wood to preserve them from the thousands of pilgrims who climbs them on their knees. The rate of progress as you move up each step is very slow and is suitably punishing as it is extremely hard and uncomfortable on your knees. Every few steps you will see small holes cut through where supposedly the Blood of Christ dropped.
