The 2,300-room Palace of Versailles just outside of Paris receives a seemingly constant stream of repairs. Just last year, for instance, an American-French coalition launched a restoration inside the state apartment of Sun King Louis XIV . Elsewhere, experts have been restoring one bedroom within the King’s Private Apartments , which Louis XV built and Louis XVI used, since the 1980s. Now, that project has finally come to an end. Crews just placed the very last details replicating precisely what this princely bedroom looked like on October 6, 1789—the very day that the French royal family made its final departure from Versailles.

Louis XV’s beleaguered reign lasted pretty much his entire life, from 1715 to 1774. During that time, he made scores of additions to his father’s grandiose palace, including a suite of more secluded private apartments, spanning dining rooms, laboratories, and more.
