The abbey of Saint Denis became a royal necropolis with the burial there of Dagobert I in the 7th century, confirmed as such by the burials of Charles Martel and Pepin the Short, and became an anchor shrine of the French monarchy under the early Capetian dynasty. Major donors also included Charles the Bald in the 9th century, Louis VI and Louis VII at the time when Suger was both the Saint-Denis abbot and a key royal adviser, Philip II, Saint Louis, and other French monarchs. As centuries went by, many objects acquired a semi-mythical aura and were given anachronistic labels as having belonged to Solomon, Saint Denis, Dagobert, Charlemagne, Roland, Saint Louis, and other iconic figures of the past.

A number of the treasury's precious objects, including the main royal crown, were destroyed during the French Wars of Religion. In 1706, the treasury was described in detail by the Maurist scholar Michel Félibien in his Histoire de l'abbaye royale de Saint-Denys en France, including engravings of the precious objects, at a time when they were kept in seven large wooden closets.^[1]

Many others objects were looted or destroyed during the turmoil of the French Revolution. A number of objects, including the throne of Dagobert, were transferred to the National Library in September 1791. In 1792, following legislation in May that abolished congregations, religious activity stopped at the abbey. Turmoil followed a year later, as the royal necropolis was desecrated in October 1793. On 5 December 1793, some of the treasury's objects were deposited in the Louvre museum. Other were sold in July 1798, such as the 7th-century "brooch of Dagobert”.^[2] Even among the objects that had been taken under public custody, some were stolen, in 1795 from the Louvre and in 1804 from the Bibliothèque nationale. Others were stolen in 1830.^[3] Meanwhile, the reconstituted canons of Saint-Denis acquired several ancient objects to replenish their treasury, and others were donated by the monarchs during the Bourbon Restoration, but a number of these were stolen again in 1882. A few additional items disappeared during the 20th century.^[4]

In 1991, the treasury of Saint-Denis was the theme of an exhibition at the Louvre.^[5]

• Two near-identical crowns both known successively as the Crown of Charlemagne (or alternatively, of Saint Louis), actually the coronation crowns of Philip II of France and his wife Ingeborg of Denmark. These were donated to the abbey by Philip in 1223, then taken back by Louis VIII and donated again by Saint Louis in 1261. The king's crown was melted in 1590 by Charles de Guise during the Catholic League's rule in Paris. The queen's crown was subsequently used as a substitute and correspondingly also known as the Crown of Charlemagne; a still-extant emerald known as the émeraude de Saint Louis is believed by some scholars to be from that crown.^[6] Another crown, known as the Crown of Joan of Évreux,^[7] was used for the queens' coronation. Both disappeared in 1793 during the French Revolution.
• The early Bourbon kings had two crowns each made for their coronation, one of gold and the other silver-gilt: the Treasury kept the corresponding six crowns of Henry IV, Louis XIII and Louis XIV. It also had funeral crowns created for Anne of Austria, Maria Theresa of Spain, Henrietta Maria, Philippe of Orléans, and Maria Anna Victoria of Bavaria.^[8]
