In the Grands Boulevards district of Paris, the Hôtel de Mercy-Argenteau, a magnificent 18th-century town house, opens its doors to the public for the first time. Listed as a Monument Historique, this architectural gem has been given a facelift to house the École des Arts Joailliers. In January 2024, it will host the first free exhibition of the Comédie-Française's stage jewelry, a treasure not to be missed.
