A Living Collection
The Treasury Museum of St. Peter's Basilica displays what remains of the legendary Treasury of Saint Peter—a collection essentially consisting of liturgical objects once used for sacred functions in the Basilica, but now withdrawn from active use. The Treasury was born alongside the Basilica itself; their histories form the warp and weft of a single narrative fabric.
Throughout the centuries, the Treasury has seen long periods of slow but continuous enrichment, interspersed with moments of sudden and dramatic loss. The sackings of Rome took their toll—at the hands of Visigoths (410 AD), Vandals (455), Ostrogoths (545), Saracens (830, 846), Normans (1084), and the Landsknechts (1527). During the Jacobin occupation (1798-1799), the collection suffered further severe requisitions.
Resilience Through Devotion
After each traumatic loss, the Treasury was always reformed—based on what survived and enriched by generous benefactors who wished to leave a tangible sign of their devotion to the Apostle Peter.
Guardians of the Treasury
Since the eleventh century, the Chapter of Saint Peter has been entrusted with the liturgical officiating of the Vatican Basilica—and with it, the custody of the Treasury's liturgical objects, vestments, and sacred vessels.
Until the early twentieth century, the Treasury was not open to the public; canons showed it to scholars or distinguished guests only upon special request. In 1909, a first museum arrangement was created with just two rooms. Beyond the liturgical objects, items linked to the Basilica's history and notable works of art were also displayed.
The Modern Museum
The most significant transformation came in preparation for the 1975 Jubilee, when architect Franco Minissi completely revised the display criteria. The focus shifted to emphasizing individual works, according to the principle of the "protagonism of the objects" on display.
Today, more than fifty years after that redesign and in view of upcoming Jubilee celebrations, a new project for the redevelopment and enhancement of the Museum is being studied, ensuring this remarkable collection continues to inspire future generations.
