As the world’s smallest sovereign state, Vatican City hides a one-of-a-kind locksmith role that safeguards thousands of priceless artworks across the Vatican Museums. This unique profession belongs to Gianni Crea, the chief clavigero — the official head locksmith and key keeper of the entire museum complex, profiled in a fresh April 2025 exclusive interview by National Geographic France.

    The stunning, soft-lit photograph accompanying the feature instantly draws viewers in: a close-up shot of Crea’s hand gripping a massive ring loaded with dozens of antique and modern keys, set against warm yellow stone archways of the Vatican’s historic corridors. The gentle morning shadow stretches across the wall, framing the heavy key cluster and telling a quiet story of centuries of heritage under lock and key.
Crea has served the Vatican for 27 years, and taken the lead locksmith position for more than a decade. Every single day, long before tourists flood the galleries, he begins his solemn routine at dawn. He first enters a climate-controlled secure underground bunker, where all 2,797 dedicated keys are safely stored to avoid rust and damage. Each key unlocks one of the museum’s 300 separate spaces, covering ancient Egyptian exhibition halls, Raphael’s fresco chambers, tapestry galleries, and the iconic Sistine Chapel.
    Among the collection sits irreplaceable historic keys: a 1700s forged iron key weighing nearly half a kilogram for the oldest museum wing, and an unmarked sealed key reserved solely for the Sistine Chapel, locked away in a sealed envelope every night. Crea and his small team walk roughly 7.4 kilometres each shift to open and lock every doorway before and after opening hours.
     In the National Geographic France interview, Crea shared his humble perspective on his rare job. Though officially the chief locksmith of the world’s tiniest country, he considers himself simply a doorman who unlocks doors to global art and Christian history. For him, wandering silent empty galleries at sunrise, surrounded by masterpieces unseen by crowds, is a quiet privilege few people on Earth will ever experience.
He describes the weight of responsibility carried in every metal key on his ring — each one links to centuries of papal history, irreplaceable paintings, marble sculptures, and sacred relics. Weekly, his team inspects every lock and key to guarantee flawless security for the Vatican’s unmatched cultural collection.
This vivid photographic feature shines a light on an overlooked essential trade within Vatican City. Far more than an ordinary locksmith, Gianni Crea acts as a silent custodian, guarding access to some of humanity’s most valuable artistic heritage hidden inside the world’s smallest nation.
