Fragment taken from the Holy Cross first discovered by St. Helen in a dry cistern in Jerusalem, and subsequently brought back to Rome (324 A.D.) The fragment is displayed in a large, gilded 35" tall reliquary housing other relics, also related to Christ's Passion.

On the right hand side, divided in quarter sections, features a thread from the Shroud of Turin (upper right), olive wood fragment from the Titulus Crucis (lower right), square piece form the *Surdarium of Oviedo (lower left) and the piece of the sponge (upper left).

The blood seen on the Sudarium of Oviedo matches the blood type on the Shroud of Turin.
