Under the main altar, in the sunken confession chapel, lies one of the most sacred relics in Christendom: the Holy Crib. These five humble pieces of sycamore wood are believed to be part of the manger where Jesus was laid in Bethlehem, brought to Rome in the seventh century for safekeeping. Paradoxically, just a few feet away from this gold-encrusted reliquary, you will find the resting place of a giant of art history. To the right of the high altar, look for a simple stone slab in the floor with a modest Latin inscription. This is the tomb of Gian Lorenzo Bernini, the architect of Saint Peter’s Square and the master of the Baroque style. After a life of creating the most extravagant monuments in the city, he chose to be buried here in total simplicity, reflecting his personal devotion to this basilica. A quick practical reminder: as this is an active place of worship and a Papal site, please ensure your shoulders and knees are covered to respect the strictly enforced dress code.
