Conservation of the Shroud of Turin

The conservation of the Shroud of Turin refers to the conservation-restoration and enduring preservation of the Shroud of Turin to avoid further damage and contamination. Since 1578 the Shroud is kept in the Royal Chapel of Turin Cathedral (from 1694 to 1993 the Shroud rested in the Royal Chapel's Bertola altar), under the laminated bulletproof glass of the airtight case. The temperature and humidity controlled-case is filled with argon (99.5%) and oxygen (0.5%) to prevent chemical changes, the Shroud itself is kept on an aluminum support sliding on runners and stored flat within the case.
