In Search of Holy Treasure S01E10 - The Tunic of Argenteuil and the Robe of Trier

In 1152, the Benedictine monks of St. Denis (north of Paris), undertook major restoration works at the Argenteuil monastery. While piercing one of the surrounding walls, they discovered a passage leading beneath the building. There, in a cellar forgotten for 200 years, they discovered an ivory chest containing a neatly folded tunic; said to be the tunic of Christ.
