At the behest of Duchess of Savoy Marguerite of Austria, the Shroud is no longer moved around with the Savoys during their travels, but given a permanent home in the Royal Chapel of Chambéry Castle. Duke Philibert, Duchess Marguerite, Francois of Luxembourg, viscount of Martigues, husband of Louise of Savoy (grand-daughter of Duke Louis), together with nearly all the local clergy, attend the ceremony of translation during which Laurent Alamand, bishop of Grenoble, solemnly carries the Shroud in its silver-gilt case from Chambéry’s Franciscan church to the Sainte-Chapelle. The Shroud is displayed on the Chapel’s high altar, then entrusted to the care of archdeacon Jacques Veyron and the canons of the Chapel, who replace it in its case and deposit it behind the high altar, in a special cavity hollowed out of the wall. In this cavity it is secured by an iron grille with four locks, each opened by separate keys, two of which are held by the Duke. Pope Sixtus IV confers on the Chambéry chapel the title Sainte Chapelle.

In Dec 4, 1532, there is a fire in the Sainte Chapelle in Chambery. The major burn marks on the shroud are a result from this fire.
Fire breaks out in the Sainte Chapelle, Chambéry, seriously damaging all its furnishings and fittings. Because the Shroud is protected by four locks, Canon Philibert Lambert and two Franciscans summon the help of a blacksmith to prise open the grille. By the time they succeed, Marguerite of Austria’s Shroud casket/reliquary as made to her orders by Lievin van Latham has become melted beyond repair by the heat. But the Shroud folded inside is preserved bar being scorched and holed by a drop of molten silver that fell on one corner.
