Relics of the apostle Saint Andrew are stored in the church.
They consist of the small finger, part of the top of the cranium of the Apostle,
and small portions of the cross on which he was martyred, all kept in a special shrine.
The holy skull of the Apostle was sent there from St. Peter's Basilica, Rome in September 1964,
on the orders of Pope Paul VI, and placed in a special silver mitre.
