Notre-Dame De Reims By Gérard Rondeau.

The treasury, kept in the Palace of Tau, includes many precious objects, among which is the Sainte Ampoule, or holy flask, the successor of the ancient one that contained the oil with which French kings were anointed, which was broken during the French Revolution, a fragment of which the present Ampoule contains.
Notre-Dame de Reims cathedral, the former Abbey of Saint-Remi, and the Palace of Tau were added to the list of UNESCO World Heritage Sites in 1991.
