The stairs have not been seen without their wooden protection for almost 300 years. The opening was just in time for the many tourists that are heading their way to the Vatican for Easter.
Housed in a building across from the Basilica of St. John the Lateran in Rome, the stairs were brought from Jerusalem to Rome in the fourth century by the Emperor Constantine's mother, St. Helena after Christianity became the religion of the Roman Empire.
Since the Middle Ages, millions of believers have climbed the stairs on their knees to pray and meditate on Christ's passion.
"The newly restored frescoes help the faithful connect with the holy history," Father Francesco Guerra told ABC News.
