What is hidden in the Vatican

THE VATICAN'S DARK SECRETS ARE EXPOSED
With an area of around 110 acres and a population of around 1,000 people, Vatican City is the world's smallest country, completely enclosed within the city of Rome, but its modest physical size conceals its significantly outsized influence and authority. Vatican City, as the seat of the Holy See, the pope's jurisdiction, serves as the command center for the Catholic Church, the world's oldest and largest continuously operational religious organization.
St. Peter's Basilica, the Sistine Chapel, and the Vatican Museums are all located in Vatican City, making it an important cultural center. It's very significant. And, as the center of the world's largest religious denomination, it's supposed to be a valuable and holy site where God is present.
